# movmax

Moving maximum

## Syntax

## Description

`M = movmax(`

returns
an array of local `A`

,`k`

)`k`

-point maximum values, where
each maximum is calculated over a sliding window of length `k`

across
neighboring elements of `A`

. When `k`

is
odd, the window is centered about the element in the current position.
When `k`

is even, the window is centered about the
current and previous elements. The window size is automatically truncated
at the endpoints when there are not enough elements to fill the window.
When the window is truncated, the maximum is taken over only the elements
that fill the window. `M`

is the same size as `A`

.

If

`A`

is a vector, then`movmax`

operates along the length of the vector`A`

.If

`A`

is a multidimensional array, then`movmax`

operates along the first dimension of`A`

whose size does not equal 1.

`M = movmax(___,`

specifies the
dimension of `dim`

)`A`

to operate along for any of the previous syntaxes.
For example, if `A`

is a matrix, then
`movmax(A,k,2)`

operates along the columns of
`A`

, computing the `k`

-element sliding maximum
for each row.

`M = movmax(___,`

specifies
whether to omit or include `nanflag`

)`NaN`

values in `A`

.
For example, `movmax(A,k,"includenan")`

includes all
`NaN`

values when computing each maximum. By default,
`movmax`

omits `NaN`

values.

`M = movmax(___,`

specifies
additional parameters for the moving maximum using one or more name-value arguments.
For example, if `Name,Value`

)`x`

is a vector of time values, then
`movmax(A,k,"SamplePoints",x)`

computes the moving maximum
relative to the times in `x`

.
