Neural Network Toolbox: "out of memory" error

Hello,

I am using the Neural Network Toolbox for creating forecasting models.

I have not faced any problems when dealing with matrixes of 10x3500 size until recently when I tried to create a "while" loop. I use such matrixes as training data.

I got an "out of memory error" and every time I am trying to enter the same matrix (the 10x3500) I get the memory error.

After that memory error created from the loop command I cannot anymore train a NN with the specific matrix.

Using a different pc I deal succesively with this matrix with no Matlab memory errors.

I use Matlab2012b on a 64-bit system with 8GB RAM.

On the other system I use Matlab2011a (32-bit and 4GB).

Any help?

Thank you very much.

Pavlos
