Subject: Vector comparison to matrix
I am looking for a fast way to count the number of rows in a matrix are
identical to a pattern vector. For example, if I am interested in counting
the number of row vectors in a matrix that are identical to (1,2,3) what
would I do? I have tried the identical statement in a loop but this is far
too slow. I have a very large matrix and need to avoid loops at all costs.
Thanks for any help.
