Function: wilframediag
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.
