so I just want to check if there are any equivalent elements between two randomly generated matrixes. I use the following code:
X=rand(100)
Y=rand(100)
C=intersect(X,Y,1:100)
and I get the following error:

Error using ==> intersect at
160
Unknown flag.
Any ideas on what I'm doing wrong? When I use the intersect function on two straight 1-row vector that I purposefully put some equal elements into, it works just fine. Like, if I was to do:
A=[1;2;6;3;5;8]
B=[4;6;9;7;4;5]
C=intersect(A,B)
I'd get C=[5,6] which makes sense.
I read in MATLAB that you can use the intersect function with matrices as long as you also specify which rows you wanna look at...
Anyways, I would really appreciate any help and thanks for looking!
