The Christmas wish of my wife: A bath room scale designed and manufactured by Volkswagen, which is able to recognize whether she or me is standing on it. And when the scale senses that my wife is standing on it, the scale should show 5 kg less than it shows with me standing on it.

CMAT (Copyright Wolfgang M. Hartmann)

CMAT is just another interactive language which is an extension of C for matrix algebra and nonlinear optimization and estimation. That means, for scalar operations, the syntax of CMAT is compatible with that of the C language. Even though CMAT is similar to Gauss, MATLAB, and IML; it is not a clone of any of these. CMAT is in some degree self learning.
Data types are string, integer, real, and complex. Objects may consist of mixed data type (string and numeric). No special routines are necessary for sparse matrix algebra, CMAT decides for sparse operations whenever a specified percentage of zeros are present.
CMAT interprets in the first run through the input code. At each following pass, assembler code is executed, saving some computer time.
CMAT is using software packages like BLAS and LAPACK. Among many other functions CMAT permits the optimization of smooth and nonsmooth objective functions, quadrature of multidimensional integrals, the iterative solution of large linear systems, has an interface to ARPACK, includes a wide range of probability functions, a number of robust and nonlinear estimation methods, among them ML regression and GLIMs with fixed and random effects, and contains an advanced multi-sample SEM implementation with a variety of bootstrap methods. It has a number of features for nonnormal data, like Satorra-Bentler robust chisquare, robust ASEs, and Bollen-Stine bootstrap. It incoporates feature (variable) selection algorithms that work easily up to 100,000 variable's. It comes with a small frontend written in Tcl/TK.
Wolfgang works on CMAT since Walee moved to New Orleans and and it became clear to Wolfgang that working overtime at SAS would not be honored anyway.
Here is a short summary manual describing the elements of the language and here some more information about CMAT including some more technical papers.

Make Your Own Kind Of Music

(Performed by "Mama Cass", Lyrics by B. Mann and C. Weil)
Nobody can tell ya;
There's only one song worth singin'.
They may try and sell ya,
'cause it hangs them up
to see somone like you.

But you've gotta make your own kind of music
sing your own special song,
make your own kind of music even if nobody
else sing along.

So if you cannot take my hand,
and if you must be goin',
I will understand.

You're gonna be knowing
the loneliest kind of lonely.
It may be rough goin',
just to do your thing's
the hardest thing to do.

But you've gotta make your own ...

So if you cannot take my hand,
and if you must be goin',
I will understand.

You gotta make your own kind of music
sing your own special song,
make your own kind of music even if nobody
else sings along.


Bob Dylan: The Times They are A-Changin

Come gather 'round people
Wherever you roam
And admit that the waters
Around you have grown
And accept it that soon
You'll be drenched to the bone.
If your time to you
Is worth savin'
Then you better start swimmin'
Or you'll sink like a stone
For the times they are a-changin'.

Come writers and critics
Who prophesize with your pen
And keep your eyes wide
The chance won't come again
And don't speak too soon
For the wheel's still in spin
And there's no tellin' who
That it's namin'.
For the loser now
Will be later to win
For the times they are a-changin'.

Come senators, congressmen
Please heed the call
Don't stand in the doorway
Don't block up the hall
For he that gets hurt
Will be he who has stalled
There's a battle outside ragin'.
It'll soon shake your windows
And rattle your walls
For the times they are a-changin'.

Come mothers and fathers
Throughout the land
And don't criticize
What you can't understand
Your sons and your daughters
Are beyond your command
Your old road is
Rapidly agin'.
Please get out of the new one
If you can't lend your hand
For the times they are a-changin'.

The line it is drawn
The curse it is cast
The slow one now
Will later be fast
As the present now
Will later be past
The order is
Rapidly fadin'.
And the first one now
Will later be last
For the times they are a-changin'.

And the Band Played Waltzing Matilda:

When I was a young man I carried me pack
And I lived the free life of the rover
From the Murray's green basin to the dusty outback
I waltzed my Matilda all over
Then in 1915 my country said: Son,
It's time to stop rambling, there's work to be done
So they gave me a tin hat and they gave me a gun
And they sent me away to the war

And the band played Waltzing Matilda
When the ship pulled away from the quay
And amid all the tears, flag waving and cheers
We sailed off for Gallipoli

It well I remember that terrible day
When our blood stained the sand and the water
And how in that hell they call Suvla Bay
We were butchered like lambs at the slaughter
Johnny Turk, he was ready, he primed himself well
He rained us with bullets, and he showered us with shell
And in five minutes flat, we were all blown to hell
He nearly blew us back home to Australia

And the band played Waltzing Matilda
When we stopped to bury our slain
Well we buried ours and the Turks buried theirs
Then it started all over again

Oh those that were living just tried to survive
In that mad world of blood, death and fire
And for ten weary weeks I kept myself alive
While around me the corpses piled higher
Then a big Turkish shell knocked me arse over head
And when I awoke in me hospital bed
And saw what it had done, I wished I was dead
I never knew there was worse things than dying

Oh no more I'll go Waltzing Matilda
All around the green bush far and near
For to hump tent and pegs, a man needs both legs
No more waltzing Matilda for me

They collected the wounded, the crippled, the maimed
And they shipped us back home to Australia
The armless, the legless, the blind and the insane
Those proud wounded heroes of Suvla
And when the ship pulled into Circular Quay
I looked at the place where me legs used to be
And thank Christ there was no one there waiting for me
To grieve and to mourn and to pity

And the Band played Waltzing Matilda
When they carried us down the gangway
Oh nobody cheered, they just stood there and stared
Then they turned all their faces away

Now every April I sit on my porch
And I watch the parade pass before me
I see my old comrades, how proudly they march
Renewing their dreams of past glories
I see the old men all tired, stiff and worn
Those weary old heroes of a forgotten war
And the young people ask "What are they marching for?"
And I ask myself the same question

And the band plays Waltzing Matilda
And the old men still answer the call
But year after year, their numbers get fewer
Someday, no one will march there at all

Waltzing Matilda, Waltzing Matilda
Who'll come a-Waltzing Matilda with me?
And their ghosts may be heard as they march by the billabong
So who'll come a-Waltzing Matilda with me?


Johnny Cash: And the Man Comes Around

"And I heard, as it were,
the noise of thunder. One of the four beasts saying:
'Come and see.' and I saw, and behold a white horse"

There's a man goin' 'round takin' names,
And he decides who to free and who to blame.
Everybody won't be treated all the same,
There'll be a golden ladder reachin' down.
When the man comes around.

Till Armageddon no shalam, no shalom.
Then the father hen will call his chickens home,
The wise man will bow down before the throne.
And at his feet they'll cast their golden crowns,
When the man comes around.

The hairs on your arm will stand up,
At the terror in each sip and in each sup.
Will you partake of that last offered cup,
Or disappear into the potter's ground?
When the man comes around.

Whoever is unjust let him be unjust still.
Whoever is righteous let him be righteous still.
Whoever is filthy let him be filthy still.
Listen to the words long written down,
When the man comes around.

Hear the trumpets hear the pipers.
One hundred million angels singin'.
Multitudes are marchin' to the big kettledrum.
Voices callin', voices cryin'.
Some are born and some are dyin'.
It's alpha and omega's kingdom come,
And the whirlwind is in the thorn tree.
The virgins are all trimming their wicks,
The whirlwind is in the thorn tree.
It's hard for thee to kick against the pricks.

Hear the trumpets hear the pipers.
One hundred million angels singin'.
Multitudes are marchin' to the big kettledrum.
Voices callin', voices cryin'.
Some are born and some are dyin'.
It's alpha and omega's kingdom come,
And the whirlwind is in the thorn tree.
The virgins are all trimming their wicks,
The whirlwind is in the thorn trees.
It's hard for thee to kick against the prick,
In measured hundredweight and penny pound,
When the man comes around.

"And I heard a voice in the midst of the four beasts.
And I looked, and behold a pale horse.
And his name that sat on him was Death.
And hell followed with him."

Playing Chess with the Stasi

Movie

That movie describes the events that moved me from a well paid employment of the East German Academy of Sciences in Berlin to the West. Now it is also available here on YouTube especially when your internet connection is too slow to watch it from the link above. Copyright Thorarinn R. Einarsson and Wolfgang M. Hartmann.
Here is a scanned version of the "Zufuehrungsprotokoll" from my public protest at the Altmarkt in Dresden. And here the first page of my court sentence. Both, the SED judge Mueller and the Stasi prosecutor Wagner (with his East German salary on the list of Stasi employees), are being paid now about five times as much pension than I have! And that is probably similar to ninety percent of all former political prisoners. So much to that unification treaty signed by Kohl and Schaeuble!
