Does it have a 100-mil header for GPIO?

Buy an FTDI UM245R module from Digikey for $20 and it'll give you a USB-to-Serial interface to the board. The FPGA interfaces to the UM245R via an 8-bit parallel FIFO mode (8-bits data, and 4 control signals for the FIFO).

MATLAB can then talk to the board like its a serial port.

Cheers,

Dave
