Hi

I use a loop to fit a model to several different datasets, loading and storing for each dataset several matrices and graphs. It seems that the calculations get slower and slower the more the loop progresses and sometimes the run just crashes. I assume this is due to the large amount of data stored in Maple's memory. Is there a way to empty the memory after I've exported or saved the matrices or graphs?

Thanks, Marjet

Hi

I'm trying to work out how the Global Optimization Toolbox works and I thought I got it working. However, when I increase the ranges of the parameters over which the Toolbox should look for the solution (but still including the previous range), the outcome of the optimization changes, i.e. the toolbox finds different optimal parameter values and a different, and often higher, Sum of Squares (which is my evaluation criterium). I don't understand what I'm doing wrong!

An example:
