Compute the Standard Deviation
Compute the standard deviation of a 3-by-2 matrix input, dsp_examples_u
, using the Standard Deviation block.
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.
disp('Data Input') disp(dsp_examples_u) disp('Standard Deviation Values') disp(std_val)
Data Input 6 1 1 3 3 9 -7 2 2 4 5 1 8 6 0 2 -1 5 -3 0 2 4 1 17 Standard Deviation Values 2.5166 4.1633 6.2450 1.5275 4.9329 2.0817 2.6458 8.8882 0 0 0 0
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.
