Hello! I have two coupled differential equations: dx/dt = -(f2+r1) x + r2 y + f1 c0 dy/dt = f2 cM x - f2 x y - r2 y As you can see I have five different parameters f1, f2, r1, r2, cM I also have two sets of measurements (x[t], y[t]) Is it possible to let Mathematica search for the parameter set which produces the best fit to the measured values? Thanks! Alex
