WILFRAMEDIAG Diagonal of Wilson and WMDCT frame operator Usage: d=wilframediag(g,M,L); Input parameters: g : Window function. M : Number of channels. L : Length of transform to do. Output parameters: d : Diagonal stored as a column vector WILFRAMEDIAG(g,M,L) computes the diagonal of the Wilson or WMDCT frame operator with respect to the window g and number of channels M. The diagonal is stored a as column vector of length L. The diagonal of the frame operator can for instance be used as a preconditioner.
