It is possible to use the USB-Blaster to establish a connection between the host PC and logic within the device. Altera don't make it convenient though.
The JTAG-to-Avalon-MM master interface can be added to an SOPC or Qsys system. This component allows you to read or write via JTAG.
Unfortunately, Altera only provides procedures to use the JTAG-to-Avalon-MM master from SystemConsole, which makes it a little trickier to use from MATLAB. You have to create a Tcl server that runs in SystemConsole, and then use sockets from MATLAB to get SystemConsole to access the hardware for you.
The latest version of Quartus is required, since SystemConsole in that version has support for fileevent, which is needed to run a server.
