- Okay, here's an improvement, at least it should be since 1) it doesn't use
- for loops in matlab, and 2) has far fewer function calls. But I didn't
- benchmark it. Whenever I see those for loops I like to find ways to get
- rid of them with matrix operations.

- function T=mat2str(X,nc)
- %MAT2STR
- % T=mat2str(X) converts matrix X into string format T, using sprintf
- % to convert each element of X.
- % T=mat2str(X,nc) uses nc characters for each column, instead of
- % default 12.

- if nargin<2,
- nc=12;

-
- [mx,nx]=size(X);
- T = reshape([setstr(X+'0'); ' '*ones((nc-1)*mx, nx)], mx, nx*nc);
