meyeraux

Meyer wavelet auxiliary function

Syntax

Y = meyeraux(X)

Description

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

$y = 35 x^{4} - 84 x^{5} + 70 x^{6} - 20 x^{7} .$

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