Create Haar wavelet transformation matrix H for the matrix vector
multiplication implimentation of Haar wavelet transformation.
This function uses the following nice formula to create the Haar
H_n=1/sqrt(2)[H_(n/2) kron (1 1)
I_(n/2) kron (1 -1)],
where 'kron' denotes the kronecker product.
The iteration starts with H_1=. The normalization constant 1/sqrt(2)
ensure that H_n^T*H_n=I, where I is identity matrix. Haar wavelets are the
rows of H_n.

its works but I am trying to solve the pdes with haar transform so need some more details
How to compute the inverse of this matrix?
i need it in 3D
i have a question i need to do wavelet transform using characteristic function at critical points -1 to 1 ,,,how do i do it ,,,,,,
thanks for the post!!!!, it works
