Function: quadtfdist

QUADTFDIST Quadratic time-frequency distribution
  Usage p = quadtfdist(f, q);

  Input parameters:
        f  : Input vector:w
        q  : Kernel

  Output parameters:
        p  : Quadratic time-frequency distribution

  For an input vector of length L, the kernel should be a L x L matrix.
  QUADTFDIST(f, q); computes a discrete quadratic time-frequency 
  distribution.
