- Subject: matrix rank
I'm getting shot down by antispam software every time I post, so I'll
make this up out of several short messages. First, for list
statisticians -- I need to evaluate the rank of an MxN (possibly square)
integer matrix. Is the best routine for this purpose one of the SVD
routines or something else? I could write one, but I'm trying to use
GSL code where I can as it is likely better than a simple pivoted
elimination (and I don't have to write it:-)
Code examples would be great if they are handy.
