row_max =
3×3 logical array
0 0 1
0 0 1
0 0 1
col_min =
3×3 logical array
1 1 1
0 0 0
0 0 0
I have these logical arrays. I want to find the intersection index of them where there must be the same element in the same index. In this example I would need (1,3), since it would be the same element and at the same index at col_min(1,3) and row_max(1,3). Thanks.

[r, c] = find((row_max&col_min)==1);

The eq is not required:
[r,c] = find(row_max&col_min);

I agree that it is not required, however it might be a useful point to note for OP, as a similar approach might be applied later.

"... however it might be a useful point to note for OP, as a similar approach might be applied later"
By definition, superfluous code never needs to "be applied later", and usually indicates a misunderstanding of MATLAB.
