Hi,
I have A = [123; 312]. How can I find the position of the digit 3 in each element of A? That is, I want B = [3; 1].
Any help would be appreciated.

Ran in:
A = [123; 312]
A = 2×1
123 312
B = cell2mat(strfind(string(A), '3'))
B = 2×1
3 1
This will fail if any entry does not have exactly one 3. And watch out for floating point data, string() will round it.
