# orderspectrum

Average spectrum versus order for vibration signal

## Syntax

## Description

`[`

computes
an average order-magnitude spectrum vector starting from an order-RPM
map and a vector of orders. Use `spec`

,`order`

]
= orderspectrum(`map`

,`order`

)`rpmordermap`

to
compute `map`

and `order`

. `map`

must
be linearly scaled. The returned amplitudes are the same as in `map`

.
The returned spectrum is scaled linearly.

`orderspectrum(___)`

with no
output arguments plots the RMS amplitude of the order spectrum, scaled
linearly, on the current figure.
