Can anyone help me write a genetic algorithm code for this in Matlab?

A,B,C,D - parameters have to be optimised in

QLC=(A*exp((-(C*Ec*Q*Cr)/(R*T)))+(B*exp((-D*Ed*Q*Dr)/(R*T)))

and the fitness function QLM-QLC has to be minimized. QLM and QLC are vectors.

Where is QLM?

Is there a reason for not using the curve fitting toolbox for this?

QLM is just a vector of numbers.

I'm not aware of a curve fitting toolbox.

This sort of application is exactly what the curve fitting toolbox is designed for.
