Function: noshearlength

NOSHEARLENGTH  Transform length that does not require a frequency shear
  Usage: L=noshearlength(Ls,a,M,lt)

  NOSHEARLENGTH(Ls,a,M,lt) computes the next larger transform length
  bigger or equal to Ls for which the shear algorithm does not require
  a frequency side shear for a non-separable Gabor system specified by
  a, M and lt. 

  This property makes computation of the canonical dual and tight Gabor
  windows GABDUAL and GABTIGHT and the DGT for a full length window
  faster, if this transform length is choosen.
