how to stop from running a program whenever any of the element become zero or gets negative?

i have a matrix A=rand(m,n); B=1-A; so when B is running in a loop for 100 times i want to end the matrix once any of the element of B becomes zero.

plz plz help me....

B will never be exactly 0 since A will never be exactly 1, at least probably not in your lifetime.

If you want to exit the loop, you can do:

if(ismember(0,B))
  break
end

If there is code after the loop, that part will be executed though. Do you have code after the loop that you do NOT want to execute?

Use the any and break functions.

Example:

for k1 = 1:100
    A = rand(10);
    B = 1-A;
    if any(B == 0)
        k1
        break
    end
end
