Indexing Logical Array Intersections

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);

Thank you very much.

The eq is not required:

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

[Dyuman Joshi]

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.
