"out of memory or dimension too large for Octave's index type"

Dear Octave Community,

 

I got this "out of memory or dimension too large for Octave's index type" issue when I was trying to create a matrix of size 5184 by 3904 in an octave command line window. The screen shot when this issue happened is attached as ‘Capture2.png’.

 

I’m sure that octave can handle/create a matrix of such size, as I can successfully create such a matrix if I restart octave cli, as shown in attached ‘Capture3.png’.

 

The only thing is that the octave program has been running for a while. But I’ve cleared all the variables by running ‘clear all’ command and results of ‘whos’ command show no variable exists in local workspace.

 

The version of octave is 4.2.1 32 bit, OS is Windows 7 64bit. I understand that switching to octave 64bit might solve this issue, but it is not a viable solution for my current situation.

 

Could anyone help me with this problem?

 

Thanks a lot!

 

Best Regards,

 

Yan
