    %% Cumulative Sum of a Matrix
%%
% *Note*: This example runs only in R2016b or later. If you are using an
% earlier release, replace each call to the function with the equivalent
% |step| syntax. For example, myObject(x) becomes step(myObject,x).

%%
% Use the |dsp.CumulativeSum| object to compute the cumulative sum of a
% matrix.
 hcsum = dsp.CumulativeSum;
 x = magic(2)
 y = hcsum(x)
 
 %%
 % The cumulative sum is computed column-wise along each channel.
