computer memory and Octave

[Tracy Feldman]

To whom it may concern:

 

I am running Octave on a laptop with windows XP.  I have been trying to run a relatively complicated bootstrap program, and I hope to run 5000 bootstrap replicates.  Octave is crashing before 180 replicates have finished, and on the screen it gives the error messages listed below the text of this message (I do not understand the message except for the first line). 

 

I wondered if anyone can discern from the error messages below if this issue is caused by problems with the program itself (too much information stored at once), by limitations of my computer, or by limitations of Octave.  When I installed Octave (April 2006), my computer had only 512 megabytes of RAM, but we have since upgraded to 768 megabytes (my computer has a maximum capacity of 1024 megabytes). Could this affect how Octave is running?  I have not been using the computer actively for any other processes while running Octave.

 

I would appreciate any help you might offer.  I hope I have given enough information.  Please reply to me directly, as I am not currently subscribed to this list.

 

Sincerely,
