Compute the Standard Deviation

Open and run the model.

The block processes the input as a two-channel signal with a frame size of three and computes the standard deviation along each column.

model = 'ex_standarddeviation_ref';
open_system(model)
sim(model)

Display the input and the standard deviation output values.

To compute the standard deviation over each row, entire input, or a specified dimension, set the Find the standard deviation value over parameter appropriately.

Close the model.
