movvar

Moving variance.

📝Syntax

R = movvar(A, window)
R = movvar(A, window, d)
R = movvar(..., nanflag)
R = movvar(..., 'Endpoints', endpoints)
[R, M] = movvar(...)

📥Input Arguments

Parameter	Description
A	input array.
window	positive scalar window length.
d	dimension to operate along: positive integer scalar.

📤Output Arguments

Parameter	Description
R	Moving variance.
M	Moving mean computed over the same windows as R (same size as R; a timetable for a timetable input).

📄Description

movvar computes variances over a centered moving window.

💡Examples

A = [1 2 8 4 5];
R = movvar(A, 3)

Moving variance and moving mean

A = [4 8 6 -1 -2 -3 -1 3 4 5];
[R, M] = movvar(A, 3)
