is provides a means of controlling several IEEE4888 (GPIB) devices and is actually a wrapper for the isX function. The isX functions form the basis of a Matlab-GPIB interface, and can be considered the lowest level of code in the Matlab environment. The ieee488 functions call isX functions, and the REKLAB_exp scripts call the ieee488 functions.
This code is located on Spindle (D:/BMED_Tools/isx). On-line help can be accessed through the Matlab 'help <function_name>.m' command. Additional information is stored in the readme file linked below.
