Setting value to zero at random

Hi Everyone,

Suppose I have two vectors

A = [0 2 2 0 1]

and

B = [1 3 4 2 1]

and suppose I apply following code:

val = max(nonzeros(A)); [~,J] = find(A == val); z(1,J) = 0;

Then the result is to change the 3 and the 4 in B to 0.

My problem is simply, that I only wish to change one place in B to 0, and the place actually changed should be chosen completely at random from those max nonzeros.

How could I adjust my code to allow this?

Regards,

Ulrik.

idx=find(max(nonzeros(A))==A);
B(randi([idx(1) idx(end)]))=0
