Gauss1D

Gauss1D (w, x)

The Gauss1D function returns the value of a Gaussian peak defined by the coefficients in the wave w. The equation is the same as the Gauss curve fit:

$$\displaystyle w[0]+w[1] \exp \left[-\left(\frac{x-w[2]}{w[3]}\right)^{2}\right] .$$

Examples

Do a fit to a Gaussian peak in a portion of a wave, then extend the model trace to the rest of the X range:

Make/O/N=100 junkg	// fake data wave
Setscale/I x -1,1,junkg
Display junkg
junkg = 1+2.5*exp(-((x-.5)/.3)^2)+gnoise(.1)
Duplicate/O junkg, junkgfit
junkgfit = NaN
AppendToGraph junkgfit
CurveFit gauss  junkg[50,99] /D=junkgfit

// now extend the model trace
junkgfit = Gauss1D(w_coef, x)
