y = dho(p, x, [y]) : Damped harmonic oscillator
iFunc/dho Damped harmonic oscillator fitting function, including Bose factor.
y=p(1)*p(3) *p(2)^2.*(1+1./(exp(abs(x)/p(5))-1))./((x.^2-p(2)^2).^2+(p(3)*x).^2)
dho(energy) creates a model with a line at specified energy (centre)
dho([ parameters ]) creates a model with specified model parameters
Reference: B. Fak, B. Dorner / Physica B 234-236 (1997) 1107-1108
input: p: Damped harmonic oscillator model parameters (double)
p = [ Amplitude Centre HalfWidth BackGround Temperature(in x units)]
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=dho([1 0 1 1], -10:10); or y=plot(dho);
