Thanks alot.
Unfortunately I can not apply this to much bigger matrices as I can not
visually check all the components.

Alex

The following returns zeros where elements do match, and NaN's
where they don't match
mat1 <- matrix(c(1,2,1,2), 2, 2)mat2 <- matrix(c(0,0,1,2), 2, 2)
mat1 %% mat2

Dear all,
I have a few matrices that are roughly the same (same dimensions).
How I can find fast which are the elements that differ?
Best Regards
Alex
