pmexican2d

Return the 2D mexican wavelet or scaling function packets

Syntax

out = pmexican2d(kx,ky,mode[,alpha])

Description

Return the 2D mexican wavelet or scaling function packets

Input Data

kx,ky

[REAL MATRIX] the frequency plane

mode

['infinit'|'scaling'|'wavelet'|'dscaling'|'dwavelet']: specify the function to return through out. So, you can have the integrated scaling function ('scaling'), the wavelet packet ('wavelet'), the duals of these (respectively 'dscaling' and 'dwavelet') useful for the reconstruction, and finally the infinitesimal wavelet ('infinit'), that is the 2D mexican hat.

Output Data

out

The frequency mask of the returned function.
