Hi

Does anyone know how to reset the memory during a large number of loops? I've read jet's post on this subject and someone mentioned garbage collection but I'm not clear how to go about doing this.

Basically what I want to do is after every 10 loops or so export the answers, keep the few variables I need and then reset the memory (equivalent to closing down maple & reopening).

Hi

Just started using the global optimization toolbox. Not sure if I am doing something wrong or if it is genuinely awful. After about 20mins it produces a fit that is dreadful,an alternative cheaper package (scop) produces a great fit in about 2 mins. Can anyone see what I'm doing wrong?

Hi

I've got an array A (size 20x3) whose elelments are plots

odw:=odeplot(q,[t,x(t)]):

A[1,1]:=display(odw):

etc

If I display(A); it prints very nicely to the screen. But when I try to print the plots on a row are all squashed up without being scaled equally in x and y and only the rows that can fit on a single page are plotted. I can export if as a gif file but thats a bit clunky. Is there no way to print directly from maple without it looking a mess?

 

thanks

Hi

When I run the attached code (basically just a big loop that doesnt do anything) it terminates early (when i is about 4600).

On my computer I get the error message "kernel connection lost".

On other computers it just stops.

It seems to be quite memory intensive but I don't understand why it terminates. normally if i run a large loop it may take a long time but it will get there eventually. I dont understand why this terminates in the middle.

 

any ideas would be great!

thanks
