Inverse Wavelet Transform
Syntax iwavelet(my)
See Also wavelet , dft

Description
Returns the inverse of the wavelet transform of y, where y is a real, double-precision or complex column vector with length equal to a power of 2. The integer scalar m specifies the number of wavelet coefficients. The forward wavelet transform is an invertible mapping; in fact, it is an orthogonal mapping (a linear mapping that maps vectors to vectors with the same norm). This function is the inverse mapping of the forward wavelet transform; that is, if y = wavelet(m, x) and z = iwavelet(m, y) it follows that z is equal to x.

Example
If you enter
     x = real(seq(8))
     y = wavelet(4, x)
     z = iwavelet(4, y)
     print z'
O-Matrix will respond
     [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]
