Changed the naming of arrays from ArRaY[0,0,0] to ArRaY__0:0:0:__ This involved changes in PG.pl and PGmorematrixmacros (ans_array_filter) Made other cosmetic fixes to code. Added names to many filters to help with debugging. It seems to work for now.
removed unneeded #! line
fixed #! line
Removed the last change, it's now handled in display_matrix.
Added a pretty_matrix sub routine to fix some rounding problems.
Added a vec_solution_cmp. Used for problems where the answer needs to be v1_s*v2+t*v3 where v1,v2,and v3 are vectors. v1 has to be a linear combination of the professors answer where the first one has a nonzero coefficient. The others are a basis, and are compared with compare_basis.
Matrices now displayed in previewer.
committed the wrong thing
fixed a bug
Made the code more object-oriented
Matrices now take math constants.
Student answer now displayed in a html table given by jones's display matrix method in PGmatrixmacros. The braces were giving me headaches so I set the option to none, at least for now.
Was not accepting negative answers, the sign problem is fixed now.
Ok, there is the ans_array_filter added which allows for the answer to be coming from the ans_array.
remove unneccsary shebang lines Arnie
