Parameter estimation for an epidemic model

I have an epidemic model:

function ypsirid = ypsirid(t,y)
global q m b r
ypsirid(1) = q - m*y(1) - b*y(1)*y(2);
ypsirid(2) = (b*y(1)*y(2)) - (m+r)*y(2);
ypsirid(3) = (r*y(2)) - m*y(3);
ypsirid = ypsirid(:)

I would like to estimate two parameters - b and r for this model. Can anyone kindly suggest the easiest possible method to do so using MATLAB.

As a guideline, take a look at

http://www.mathworks.com/matlabcentral/answers/43439-monod-kinetics-and-curve-fitting

There, parameters of a Monod kinetic have been fitted to measurements.
