y = triangl(p, x, [y]) : Triangular
iFunc/triangl Triangular fitting function
y=(p(3)-sign(x-p(2)).*(x-p(2)))/p(3)^2;
and y is set to the background outside the full width.
triangl(width) creates a model with a specified width
triangl([ parameters ]) creates a model with specified model parameters
input: p: Triangular model parameters (double)
p = [ Amplitude Centre HalfWidth 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=triangl([1 0 1 1], -10:10); or plot(triangl);
