I found that when I passed a string (passed from another function – but I don’t know if that matters) to printf using ~a, I got an error, but if I put the string inside a “string(…) function it worked. This may have been what was causing the trouble I… Continue reading →

I’ve been continuing on mu diffeq program. I call it omnisode.rb. It is to generate a program to solve numerically systems of ordinary differential equations. I am trying to make it generate code in any of Ruby, Ruby with my apfp, Maple or maxima. I have been writing small programs… Continue reading →

I continued to have problems with maxima. I decided to change direction. Now working on the program (still in Ruby) to generate code for any of Ruby, Ruby with my APFP, Maple, or (hopefully) Maxima. I’ve switched the environment from Linux to Vista as well, as that is where I… Continue reading →

I have solved some problems I was having. Just takes scouring the maxima manual!

I figured out – partly from info on the web – partly from experimentation – that the behavior of arrays in maxima – especially when passed as parameters is peculiar. Still debugging – and a long way to go – but progress being made.

I have finally figured out what had been causing my trouble with arrays. Now having another problem – but I know what it is – just too tired to fix tonight.

I’ve been doing more work on my differential equations program. Mostly learning the language – maxima – better, and verifying, in a small program, that it works the way I think it does (or should).
