I’ve been so busy on it I haven’t posted here yet in June! See Differential Equations Work

See Onnisode Home Page I sat down to watch the Celtics tonight, and soon realized I was quite tired from the last couple weeks working so hard on this. I am going to have to go a little slower.

See sample output file. Maple also echos the program.

Test results at test results Source code at Source code tar file The program is in Ruby and generates a Maple program. I have only used it under Linux and it uses a shell script as well.

A summary of my testing is at testrecords There were a few typos yesterday – hopefully they have all been corrected. The test files were OK The error was just in copying them into the table of results. I think at one time I was getting better results for the… Continue reading →

I have had 1st order equations working for a while, except when I broke things trying to fix other things. One thing I had trouble with was higher order equations. Now that is fixed. Also then there were higher order equations with derivatives on the right hand side. Now that… Continue reading →

I’ve been working hard on my differential equation program. Most of the problems (locating poles) resulted from various sorts of Maple bugs I didn’t know were possible. I don’t mean bugs in Maple itself, but rather sorts of things you can do wrong in Maple – and the sorts of… Continue reading →
