matOpen to open the file
matGetVariable to get the cell array variable
mxGetCell to get the pointer to the cell contents
mxGetPr to get the pointer to the actual data

Note that MATLAB stores the data in column order, so if you are planning on indexing into it in your C++ code you need to account for that.
