Convert string array to numerical vector

I have numbers as string array A that I'd like to convert to numerical vector B:

A = ["01";"04";"12"];
B = [1; 4; 12];

I've tried with str2num but it seems to proceed only with string scalars rather than vectors.

Any tips without loop?

Use str2double

A = ["01";"04";"12"];
B = str2double(A)

B = 3×1

1 4 12
