Did you type in "HELP MEMORY", and read your options???? Did you do what it suggested??

I have the same issue. I am running Ubuntu 9.04 and Matlab 2008a (7.6.0).

I have read the documentation on:
http://www.mathworks.com/support/tec...1100/1107.html
http://www.mathworks.com/support/tec...1100/1106.html

as well as, HELP MEMORY, but I cannot use this function:
>> memory
??? Error using ==> memory
Function MEMORY is not available on this platform.

also:

>> feature memory
??? Error using ==> feature
An unknown feature was specified

>> feature memstat
??? Error using ==> feature
An unknown feature was specified

>> feature memstats
??? Error using ==> feature
An unknown feature was specified

>> feature('memstats')
??? Error using ==> feature
An unknown feature was specified

etc...

As far as my memory is concerned, this is the dump I get directly after receiving the matlab "out of memory" error:

jono@jono-laptop:~$ ulimit
unlimited
jono@jono-laptop:~$ free -m
.............total.......used.......free.....shared....buffers.....cached
Mem:..........3616.......2221.......1394..........0........139........761
-/+.buffers/cache:.......1320.......2295
Swap:.........8189..........0.......8189


I am working with a 5x2e6 array of float numbers, and will be using them in a neural network. In my mind this is only around 80mb for the array, and maybe a few more times that for preprocessing...

Does anyone have any suggestions?

Thanks!
Jono
