// Calling Sequence
// [y]=gmonopuls(t)
// [y]=gmonopuls(t,fc)
// Parameters
// t: Real or complex valued vector or matrix
// fc: Real non-negative value or complex value or a vector or matrix with not all real values negative.
// Description
// This is an Octave function
// This function returns samples of the Gaussian monopulse of amplitude unity.
// Examples
// 1. gmonopuls([1 2 3],0.1)
// ans= 0.85036 0.94070 0.52591
// 2. gmonopuls([1 2 3],[])
// ans= 0 0 0
