y = heaviside(p, x, [y]) : Heaviside step function
iFunc/heaviside Heaviside step fitting function
y = 0*x+p(4); y(find(x >= p(2))) = p(1);
The Width parameter sign indicates if this is a raising (positive) or
falling (negative) Heaviside.
heaviside(threshold) creates a model with a specified threshold
heaviside([ parameters ]) creates a model with specified model parameters
input: p: Heaviside model parameters (double)
p = [ Amplitude Centre FullWidth 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=heaviside([1 0 1 1], -10:10); or plot(heaviside);
