@Mac Dude The limitjvmheap is false yes.  I will have to try in the morning as I am not near Maple.  I will couble the stacklimit and heap size and see what happens. 

Still need to double check the memusage in the same session ie/ Open new worksheets in seperate tabs, run up the memusage in the task manager close tabs and see if the memory is released.  Maybe if I am able to restart on the same tab, the memory is released.  Although I am wondering that maybe when one worksheet runs up the memory and is closed without restart on the same sheet the memory is not released ... I'll have to check later.

@Carl Love I'm referring to the maxheap from the launch.ini file in the bin.win folder of the Maple directory.  I am not sure if the value set in the launch.ini file is the same as a value set in kernelopts.

my jvmheaplimit is currently at 65536

@Christopher2222 actually setting maxheap=2000m will not start. 

Actaully I didn't think the maxheap size was a hardcoded limit if it was not set.  I thought it was a floating value.  Anyways I will see if the 1600m limit helps.

I'm sure sending the image to a file will definitely improve the response as Mac Dude has suggested. 

Thanks for all the insights.  I will be able to check later and do some more experimenting.

I do recall a while ago that in order to avoid some java issues one would have to add the line maxheap=700m in a maple.ini file in the main Maple directory but then I recall at some later time that it wasn't required anymore.

You mention increasing the limit to 2Gb, so will adding maxheap=2000m to maple.ini do the trick?

**edit ** I meant the launch.ini file

@Carl Love Yes I am referring to the task manager values.  I am not near Maple right now but I didn't actually record what Maple was reporting in it's window pane, only what windows was reporting in the task manager.  After restart there was no release of memory in the Windows task manager - it remained high.  Perhaps it takes a little more time to release the memory, next time I have a chance I will wait 10 minutes before closing the mserver.exe and maple.exe processes.

@Alejandro Jakubi I agree no stackexchange similarities here please.

On the old primes there were some interesting blogs which now are converted to posts, and unfortunately the child pages are no longer linked with them.  Tools for the Maple Masters and High performance programming techniques have links but are not linked with any other pages (old primes had them linked to other pages). 

Also poll questions gave another dimension of interactivity with this site.  Perhaps administrators could bring it back?

@Alejandro Jakubi Not meant to be a mindset definintion.  More so as a vague comparison.

I believe the mindset is based from the stack exchange site.

I haven't used NAG but I notice that it was integrated into Maple 14

A google search of NAG maple brings up a few links .. Introduction Maple NAG-connector brings up The Help Document that you have requested was not found

Another link NAG-Connectivity Maple features brings up You have requested a page on the Maplesoft website that is not available.


Not exactly sure what happened there.

similar to a predator prey type model 

With your production and material rate constant everything revolves around your customer order rate.

Very nicely done!  And thanks for sharing it here.

@acer yes I was thinking the same.  In any image I am sure we could trim the 10 or 20 pixels from the border without affecting the calculations to much. 

In that case we would need to run a seq to remove the border wouldn't we?

@acer Thanks that's awesome!  I'm not near Maple right now.

Would we get a slight speed up if we only dealt with, say, 3 decimal places?

loop over 1000 took 200 seconds.  To loop over the whole image will take 6771 seconds or 1.8 hours.
