int dim[3] = {400,3,1000};
plhs[0] = mxCreateNumericArray(3, dim, mxDOUBLE_CLASS, mxREAL);

Hi,
that works fine for me. I assume you use a 32bit MATLAB? The variable you create needs 960mb of memory in one piece which is most likely not available for you.
You can use the memory command (Windows only!) to see what the biggest matrix is you can allocate.
Small advice: Don't use an int for the dimensions. Use mwSize. This is a bittedness independent type.
