y = expon(p, x, [y]) : Exponential decay
iFunc/expon Exponential decay fitting function
p(2)=Tau is the exponential decay parameter, in inverse 'x' units.
y=p(3)+p(1)*exp(-x/p(2));
expon(decay) creates a model with specified decay constant
expon([ parameters ]) creates a model with specified model parameters
input: p: Exponential decay model parameters (double)
p = [ Amplitude Tau BackGround ]
or 'guess'
x: axis (double)
y: when values are given and p='guess', a guess of the parameters is performed (double)
output: y: model value
ex: y=expon([1 0 1], -0:10); or plot(expon)
