if statement: Having one image as a condition and adjusting

if statement: Having one image as a condition and adjusting another image is condition is met.

I'm dividing two images (C=A/B). Now my if the pixelintensity in B <= threshold, then the pixel in C should be changed to zero. This is my code so far:

if (B <= threshold)
        C = 0;
end

However, this does not seem to work. I also thought of first finding the indices in B which are below the threshold and then set these indices to zero, but I couldn't get that right either.

Could someone help me further with this?

If we assume that B and C are of the same dimension and that you want all elements of C to be set to zero if their corresponding element in B is less than some threshold, then you could perhaps try.

 threshold = 0.5;
 B = rand(5,5);
 C = rand(5,5);
 C(B < threshold) = 0;
