Compute the Running Mean

Compute the running mean of a 3-by-2 matrix input, dsp_examples_u, using the Mean block.

Open the model.

model = fullfile(matlabroot,'examples','dsp','ex_runningmean_ref');

The Input processing parameter is set to Columns as channels (frame based). The block processes the input as a two-channel signal with a frame size of three. The running mean is reset at t = 2 by an impulse to the block's Rst port.

Run the model.


In the Running mode, the block outputs the mean value over each channel since the last reset. At t = 2, the reset event occurs. The window of data in the second column now contains only 6.

Close the model.
