[I have a system of 3 differential equation with 9 parameters.I'm going to
find the best
parameters that lead to minimize squar of error between outputs(y1,y2,y3) of the differential
equations and the values of the outputs that measured by a meter with a special duration
.(About 120 points).I used Genetic Algorithm for this purpuse .After 15 iteration ,I'd like to use
levenberg-marquardt algorithm for better convergency of GA.I don't know how i can use
levenberg-marquardt in the case of i have a system of differential equations not a explicit
function.I also should say that the response of the equation should get by the instruction ODE
in Matlab.It doesn't have explicit solution.(It has just numerical solution).would you please give
me some directions?
Best wishes
