MATLAB Source Codes

This is a small collection of MATLAB routines.

I don't mind receiving your comments, compliments, corrections or complaints, but please be warned that I will not do your damn homework.

Available software includes:

• FEM1D, a 1D Finite Element Method solver;
• PGM_READ, reads the data from a PGM (Portable Grey Map) image file;
• POLKING, two routines, DFIELD5 and PPLANE5, for direction fields and phase planes of differential equations;
• TESTZERO, some functions f(x) suitable for testing zero finders;
