# movmedian

Moving median

## Syntax

## Description

`M = movmedian(`

returns
an array of local `A`

,`k`

)`k`

-point median values, where
each median 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 median is taken over only the elements
that fill the window. `M`

is the same size as `A`

.

If

`A`

is a vector, then`movmedian`

operates along the length of the vector`A`

.If

`A`

is a multidimensional array, then`movmedian`

operates along the first dimension of`A`

whose size does not equal 1.

`M = movmedian(___,`

specifies the
dimension of `dim`

)`A`

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

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

operates along the columns of
`A`

, computing the `k`

-element sliding median
for each row.

`M = movmedian(___,`

specifies
whether to include or omit `nanflag`

)`NaN`

values in `A`

.
For example, `movmedian(A,k,"omitnan")`

ignores
`NaN`

values when computing each median. By default,
`movmedian`

includes `NaN`

values.

`M = movmedian(___,`

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

)`x`

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

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

.
