gaussfit

PURPOSE

function that outputs a gaussian fitted value-use with nlinfit- also

SYNOPSIS

function Z = gaussfit(beta,X)

DESCRIPTION

function that outputs a gaussian fitted value-use with nlinfit- also
subtracts a baseline
Z=A.*exp^(-(x-x0).^2/(2*sigma.^2))
e.g [betanew]=nlinfit(X,Y,@gaussfit,beta0)
