y = sine(p, x, [y]) : Sine function.
iFunc/sine Sine function.
y = p(4) + p(1)*sin((x - p(2))/p(3))
sine(period) creates a model with specified period
sine([ parameters ]) creates a model with specified model parameters
input: p: Sine model parameters (double)
p = [ Amplitude Phase_Shift Period 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=sine([1 0 1 1], -10:10); or plot(sine);
