Standard deviation of input or sequence of inputs

**Library:**DSP System Toolbox / Statistics

The Standard Deviation block computes the standard
deviation of each row or column of the input, or along vectors of
a specified dimension of the input. It can also compute the standard
deviation of the entire input. You can specify the dimension using
the **Find the standard deviation value over** parameter.
The Standard Deviation block can also track the standard
deviation in a sequence of inputs over a period of time. To track
the standard deviation in a sequence of inputs, select the **Running
standard deviation** parameter.

The **Running** mode in the Standard
Deviation block will be removed in a future release. To compute
the running standard deviation in Simulink^{®}, use the Moving Standard Deviation block instead.
