suppose i have a matrix [1.22 0 2.33 3.444 1.222 0] and i want the solution to be the number of iterations between non zero values. the solution should be [1 2 1 1]

Z(xidx) = z;

this is the vector that i have.

Your vector has 6 elements and your ‘solution’ has 4.

What procedure do you use for getting the ‘solution’? What ‘rule’ do you use?
