Question

0 个投票

I have a matrix of alternating 1s and 0s. Such as A = 1 0 1 0 1 0 0 1 0 1 0 1

I want to replace the "1" with a string called "[apple]" including the brackets.

How should I do this? It keeps giving me errors.

A = [1 0 1 0 1 0 0 1 0 1 0 1];
Ac = num2cell(A);
Ac(A==1) = {'[apple]'};

If you wanted to replace 1 with [apple] and 0 with something else you could do

str_table = {'[orange]', '[apple]'};
Ac = str_table(A+1);

A = [1 0 1 0 1 0 0 1 0 1 0 1];
out = cell(size(A));
out(A>0) = {'[apple]'};

This would leave empty cells where the 0 should be.
