Let given array A with 512*512 elements are (here one sample of 4*4 is given)
5 4 6 8
9 11 30 34
12 13 13 14
how to plot a graph where x-axis contains the values of individual elements of 512*256 matrix and y-axis contain the frequency of the difference value. The frequency of difference value can be obtained as
1 -2
-2 -4
-1 -1
here the difference value can be found by subtracting the 2 consecutive elements in a row.Now suppose the original matrix A is 512*512 elements, then the difference matrix will be 512 * 256 elements.
Kindly suggest

B = A(:, 1:2:end) - A(:,2:2:end);
histogram(B, 'binmethods', 'integers')
Note: this might require a fairly recent MATLAB (I do not recall ever having seen that option before.)

It is not a problem to use double() on an array that is already double(), so leave out the conversion to int32()
