I see. I was just trying to get some metrics about the matrices I
have. I am actually curious in a more general way, to figure out which
operations are implemented for a specific type. I thought that there
might be a table somewhere showing available operations for different
matrix types. I guess the only way currently is to grep the source
code.

Thank you,
Murat
