x: Input array, specified as a real scalar, vector, matrix, or multidimensional array.
Returns
Output array, returned as a real-valued scalar, vector, matrix, or multidimensional array of the same size as x.
Details
The code 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 c(0, 1).
Examples
x <- seq(0,1, length.out =100)y <- meyeraux(x)plot(x, y, type="l", main ="Meyer wavelet auxiliary function", xlab ="", ylab ="")
