Perhaps this answer is too simplistic:

Using the MATLAB Script node, if you only need one value at a time, index the array of data and send one value at a time. (This can't be right.)

Using MATLAB batch mode, you can call a .m file that opens the data file and writes an output file. Use "System Exec.vi" to call MATLAB with the /r flag for Windows (-r for *nix) and the name of the .m file.
