Moving average of a financial time series

`movavg`

is updated to accept data input as a matrix, `table`

, or `timetable`

.

**The syntax for movavg has changed. There is no longer support for
the input arguments Lead and Lag, only a single
windowSize is supported, and there is only one output argument
(ma). If you want to compute the leading and lagging moving
averages, you need to run movavg twice and adjust the
windowSize.**

computes the moving average (MA) of a financial time series.`ma`

= movavg(`Data`

,`type`

,`windowSize`

)

adds an optional argument for `ma`

= movavg(___,`Initialpoints`

)`Initialpoints`
