MATLAB: Replacing numbers in a row

Question

Dear all,

I have a question, I want to try to replace values in a row that are greater than zero. For example, I have the array A that is:

A = [ 0 0 3 5 6 4 0 0 0 3 0 0 3 2 0].

What I want is to replace all values greater than 0 by 1.I know I can use A(A>0)=1 but I don't want to replace the individual 3 by 1 instead I want it to be zero.

I want my result to be:

A = [ 0 0 1 1 1 1 0 0 0 0 0 0 1 1 0]….instead of A = [ 0 0 1 1 1 1 0 0 0 1 0 0 1 1 0].

Is there any way I can do this and specify what individual number I don't want to replace by 1??

Thank You!!

Answer 1

Just the 3 that stands alone

result = strrep(A,[0,3,0],[0,0,0])>0;
