function [psi,x]=cmorwavf(lb,ub,n,fb,fc)
// Finds the Complex Morlet Wavelet
// Calling Sequence
// [psi,x]=cmorwavf(lb,ub,n,fb,fc)
// Parameters
// lb: Real or complex valued vector or matrix
// ub: Real or complex valued vector or matrix
// n: Real scalar strictly positive integer
// fb: Real or complex scalar value
// fc: Real or complex scalar value
// Description
// This function returns the value of the Complex Morlet Waveform defined by a positive bandwidth parameter FB, a wavelet center frequency FC on an N point regular grid for the interval [LB,UB].
// Examples
// [a,b]=cmorwavf(1,2,1,3,4)
// b=2
// a=0.0858628 -1.682D-16i
