It sounds like you may have one of the following two problems:

1. The folder containing your "wholenetwork.m" file is not added in Matlab. You can find this out by typing "which wholenetwork" in the command window. If it doesn't show you a path, you have to add the path to Matlab in "Home" -> "Set path"

2. You have a variable in your workspace called "wholenetwork". In this case, Matlab try to interpret the input arguments for your function as indexes of the variable.
