674.0. "Linear algebra, a solved problem" by MORRIS::JANZEN (Thomas Janzen LMO2/O23 296-5421) Mon Mar 09 1987 14:58

Hi
I made a linear algebra package and put it in 
TLE::Ada_Toolshed note 30, 30.1, 30.2
It does cross product, dot product, tensor products, transformations,
finds determinant, etc.  I forgot to put in triple products, darn it.

I was using it to rotate ReGIS images so that I could make 3-D stereo
pictures of, you guessed it, two pendula.  This basic program, which
I have not published because it is too simple-minded, models two
pendula, one with a pen that draws in air, and one carrying a 3-D
not pad that the pen draws on.  To get stereo, I had to rotate the image
10 or 15 degrees.

You can look at the images in Sixel on VT125, 240 at
ANT::STD:[janzen]plot0.sls, plot1.sls, plot2.sls

I added triple products.  They may work correctly.

674.2rotate solid cube ?VIDEO::OSMANEric, dtn 223-6664, weight 146Tue Mar 10 1987 19:579
Those files are "protected".  I can't see them.

Anyway, I'd be interested in seeing both the output and the program
if you've got one that displays a rotating solid cube.  Three shades,
one for each visible face, would be just dandy.

Regis or sixels will do for me !

Sorry. I will check the protection.
I can't do solids.  You can see a transparent cube rotating 10 degrees
at a time in all dimensions in
ant::std:[janzen]cubes.txt
in regis I think.

674.4Ada arithmetic packages.COUGAR::JANZENObviously IntuitiveTue Apr 07 1987 13:398
hello
my little matrix package is in TLE::ADA_TOOLSHED, probably about #30.  
It is generic now.  It only has a few basic operations.

my little complex arithmetic package is in TLE::ADA_TOOLSHED about #32 or 33.
It is generic too, now, and has sinh, cosh, cos, sin, exp, +,-,/,*, **, etc.
