MATLAB: How to set black (pixel=0 or <20) to NaN in an image

Let I be your matrix....read using imread

If you want to make pixels [0 20] to NaN..do this:

I(I>=0 & I<= 20) = NaN

MATLAB: Correlation between two row matrices

Like that, each value of "a" is correlated to each value of "b", but applying the formula of the correlation, the correlation of two single numbers is NaN. To compute the correlation correctly, traspose the input vectors

result  = corr(a', b');
