I want array value not 0 keep to new array ?

r = img(:,:,1); g = img(:,:,2); b = img(:,:,3);

% double aa; double aa;

AR = [r];

[i,j] = size(AR);

for i = 1:j

    if (AR(i) ~= 0)
        aa = [AR(i)]
    end

To get the non-zero elements of an array simply do something like:

 A = randn(100, 100); 
 A_non_zero = A( A~=0 );

This stores the non-zero elements of matrix A in the array A_non_zero.
