y = doseresp(p, x, [y]) : Dose-response curve with variable Hill slope
iFunc/doseresp Dose-response curve with variable Hill slope (sigmoid)
y = p(4)+ p(1) ./ (1+10.^((p(2)-x).*p(3)));
This is a sigmoid S-shaped curve, aka logistic.
doseresp(threshold) creates a model with a specified threshold
doseresp([ parameters ]) creates a model with specified model parameters
input: p: Dose Response model parameters (double)
p = [ Amplitude Center Slope 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=doseresp([1 0 1 1], -10:10); or plot(doseresp)
