Let a be your vector which have 0 and 1.
% get indices of 1
idx = a(a==1);
Let b be your intensity values corresponding to a.
% extract inentisity values of positions 1
b_1 = b(idx);

If matrix1 is your matrix of 0's and 1's, and matrix2 is your intensity matrix, you can get the mean intensity of matrix2 only where the values of matrix1 are 1 like this:
theMean = mean(matrix2(matrix1));
