You also have to ensure that the called function can be found by MATLAB, which means it must be on the search path . The arguments to the function are taken from the command line parameters (the first command-line parameter is the first argument, and so on). disp('This matlab program is running from command line') The parameter is a integer. For now I use matlab -nodisplay -r "functionname (argument1, argument2, argumentN);exit" But for this the function I call needs to be in the folder where I am. clc; clear all.
