Making Lookup Table from Matlab data sheet

Hi, I'm trying to make lookup table in Quartus 2. v.8.1. I think I can use a dual port RAM to make the LUT, but the original data sheet (lookup table) is large (16x48 per each table) ...

MatLab should be flexible enough to format the data according to Quartus needs. Otherwise a tcl script will do. Some kind of programming is obviously required.

I don't really understand the 16x48 point. MatLab should be expected to represent LUT data by a one-dimensional array, the 16x48 seems to be just a print format? If you're actually dealing with two-dimensional data, you have to think about a suitable mapping to FPGA embedded memory first.

The same embedded FPGA memory can be used as RAM or ROM respectively, there's no real difference, execpt for the usage of available port signals. They are all mapped to altsyncram megafunction anyway.
