There is a file named awgn.m in this directory

C:\Users\Admin\Documents\MATLAB

that precedes MATLAB's awgn.m function on your path.

When you enter:

>>which awgn

you should see something like:

toolbox\comm\comm\awgn.m

You need to either remove the directory: C:\Users\Admin\Documents\MATLAB

from your path with

rmpath('C:\Users\Admin\Documents\MATLAB');

or if you need other files in that directory, move awgn.m out of there. Delete it, or copy it to a directory not on the MATLAB path. Enter

>>path

to see everything on the MATLAB path. The "bad" awgn.m is a script and you are tyring to call MATLAB's awgn.m, but because the other path comes first, MATLAB tries to use the script like a function.
