Subject: Odp: fast way to compare two matrices
In-Reply-To: <914286.77042.qm@web120101.mail.ne1.yahoo.com>
Hi
x <- matrix(rnorm(1e6), 1000,1000)
y <- matrix(rnorm(1e6), 1000,1000)
identical(x,y)
[1] FALSE
The response is almost instant.
In case you are not satisfied with the unspecific answer be more specific
with your question.
Regards
Petr
