Syntax
w = hanning(n) w = hanning(n,sflag)
Description
w = hanning(n)
returns an n-point symmetrically sampled Hanning window in the column vector w. n should be a nonnegative integer. The coefficients of a Hanning window are
w = hanning(n,sflag)
returns an n-point Hanning window using the window sampling specified by sflag, which can be either 'periodic' or 'symmetric' (the default). When 'periodic' is specified, hanning computes a length n+1 window and returns the first n points.
Diagnostics
An error message is displayed when incorrect arguments are used:Order cannot be less than zero. Sampling must be either 'symmetric' or 'periodic'.A warning message is displayed for noninteger
n:
Warning: Rounding order to nearest integer.
