Root mean square value of input or sequence of inputs

**Library:**DSP System Toolbox / Statistics

The RMS block computes the root mean square (RMS)
value of each row or column of the input, or along vectors of a specified
dimension of the input. It can also compute the RMS value of the entire
input. You can specify the dimension using the **Find the
RMS value over** parameter. The RMS block
can also track the RMS value in a sequence of inputs over a period
of time. To track the RMS value in a sequence of inputs, select the **Running
RMS** parameter.

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