Hi all; How can I convert a "logical matrix' to the numeric one. For example B matrix is below . I want to convert it to the B2 matrix . How can I do this without using any for loops?
B= [true true true true; false true true true; false false true true];
B2=[10 10 10 10; 5 10 10 10; 5 5 10 10]
Any help would be appropriated.

in your case
B2 = B*5 + 5
OR
k = [5 10]
B2 = k(B + 1)
