Syntax

Y = meyeraux(X)

Description

example

Y = meyeraux(X) returns values of the auxiliary function used for Meyer wavelet generation evaluated at the elements of X. The input X is a vector or matrix of real values. The function is

y=35x4−84x5+70x6−20x7.

X and Y have the same dimensions. The range of meyeraux is the closed interval [0, 1].
