Inverse Window Fourier Transform
sig = IWindowFT(specgm,w,Name)
Window Fourier Transform of sig, complex matrix
window half-length used to construct specgm
string: 'Rectangle', 'Hanning', 'Hamming', 'Gaussian', 'Blackman' name of window used to construct specgm
1-d signal
supposes signal is non-periodic, i.e. zero-padded reconstruction is not exact in the border region, but it is exact in the center
