Hello,
I have an ODE15s function with 4 simultaneous equations, there are a 7 chemical kinetic rate constants (K) to derive the time changes in four parameters. I am using three of these rate constants to minimise two of the equations simultaneously to two sets of data obtained from the same experiment.
I have tried fminsearch but this only allows the minimisation of one of the functions to one of the data sets based on the difference in the sum of squares error.
I am presently trying fgoalattain to try to get two minimum SSE from two functions against the data but I cannot see how to code it, the goals are presently the SSEs but I need it to change the K values so that the SSEs are minimised. I am also looking at gamultiobj but need to work out how fgoalattain works first and if it will do the job. I have the global optimisation toolbox.
Any help or advice.
Thanks, matt
