Wavelet and Scaling Functions
[PHI,PSI,XVAL]=wavefun(wname,ITER) [PHI1,PSI1,PHI2,PSI2,XVAL]=wavefun(wname,ITER) [PSI,XVAL]=wavefun(wname,ITER)
wavefun is an utility to get scaling function phi and wavelet function psi. For orthogonal wavelets, both phi and psi are available. For biorthogonal wavelets, two scaling functions and wavelet function could be obtained. For some wavelets, only wavelet function is available.
