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 Tom

I added triple products. They may work correctly. Tom | |||||

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 ! /Eric | |||||

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. Tom | |||||

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. Tom | |||||
