Hi...
I have a matrix A= [0 0 1 1; 1 0 0 1; 0 0 0 1]. I want to find the index of the first 1 of a row and want to save in a column matrix Z. In this case Z must be: Z=[ 3; 1; 4]. I am using this command Z = find(A(1,:), 1, 'first') but unable to do for second and third row. Kindly provide necessary codes for solving this.
Thank you.

[~,Z]=max(A,[],2)
