Track and extract order magnitudes from vibration signal

returns
a matrix, `mag`

= ordertrack(`x`

,`fs`

,`rpm`

,`orderlist`

)`mag`

, that contains time-dependent root-mean-square
(RMS) amplitude estimates of a specified set of orders, `orderlist`

,
present in input signal `x`

. `x`

is
measured at a set `rpm`

of rotational speeds expressed
in revolutions per minute. `fs`

is the measurement
sample rate in Hz.

`[___] = ordertrack(___,`

specifies further options using `Name,Value`

)`Name,Value`

pairs. Some of
the options apply only to the Vold-Kalman tracking procedure.

`ordertrack(___)`

with no output
arguments plots in the current figure the time-dependent orders and
RPM values.
