Function Synopsis

y = vco(x,range,Fs)

Help text

VCO	Voltage controlled oscillator
	Y = VCO(X,Fc,Fs) creates a signal which oscillates at a frequency
	determined by the input vector X.  Fc is the carrier or reference 
	frequency, and Fs is the sampling frequency; if you input 0 for X, 
	Y will be a Fc Hertz cosine with amplitude 1 sampled at Fs Hertz.  
	The range of values for X is from -1 to 1; -1 corresponds to a 0 
	frequency output, 0 to Fc and 1 to 2*Fc.  Y is the same size as X.

	Y = VCO(X,[Fmin Fmax],Fs) scales the frequency modulation range so 
	that -1 and 1 values of X yield oscillations of Fmin and Fmax 
	Hertz respectively.  For best results, Fmin and Fmax should be in
	the range 0 to Fs/2.

       If you do not specify either Fc or Fs, VCO uses the default values
	Fs = 1 and Fc = Fs/4.

	If X is a matrix, VCO produces a matrix whose columns oscillate
	according to the columns of X.
