Function: frameaccel

FRAMEACCEL  Precompute structures
  Usage: F=frameaccel(F,Ls);

  F=FRAMEACCEL(F,Ls) precomputes certain structures that makes the basic
  frame operations FRANA and FRSYN faster (like instantiating the
  window from a textual description). If you only need to call the
  routines once, calling FRAMEACCEL first will not provide any total
  gain, but if you are repeatedly calling these routines, for instance in
  an iterative algorithm, it will be a benefit.

  Notice that you need to input the signal length Ls, so this routines
  will only be a benefit if Ls stays fixed.

  If FRAMEACCEL is called twice for the same transform length, no
  additional computations will be done.
