Input Matrix Limit with Trial Neural Network Toolbox

Is there a limit on the size of the input matrix on neural network Toolbox trial version? I have a 126,000x36 matrix of data file I am trying to import. It seems that it cuts it down to 2/3 the number of rows.

Where is the code that verifies what you have described?

I was using a version of the NSL-KDD dataset. When I linked in the input data file, MATLAB cut down the matrix from 123,000x36 to around 81,000x36.

Over the past 50 years or so I have found that , excluding outliers, most n-dimensional dimensional distributions are adequately represented by N ~ 35*n randomly chosen examples. In rare cases where that was insufficient, doubling that number proved more than sufficient.

Hope this helps,
