You could also mention constructing a matrix as a array of function values f(i,j), or as a block matrix, or by appending rows or columns to another matrix. > - Slicing.

You could add instructions on how to compute a basis for the column span and row span of a matrix - should be easy to compute using rref. > - A small discussion on mutability. > - Should I mention sparse matrices? > - Should I mention matrix expressions? I'm not sure what you mean. Also, dets, char polys, eigenvalues and eigenvectors, at least if they are rational, would be nice to have. > > The current Matrix API is a little confusing and inconsistent in > places, so I'd like to avoid any confusing parts if I can. > > Aaron Meurer > > -- > You received this message because you are subscribed to the Google Groups > "sympy" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To post to this group, send email to [email protected]. > Visit this group at http://groups.google.com/group/sympy?hl=en-US. > For more options, visit https://groups.google.com/groups/opt_out. > > -- You received this message because you are subscribed to the Google Groups "sympy" group.
