Please show us the full and exact text of the warning and/or error messages (all the text displayed in orange and/or red in the Command Window.) That exact text may help us more easily determine the root cause of the error and be able to suggest a workaround or solution.

Please don't post your code as a screenshot. Please instead post it as formatted text, e.g.,
as well as a .mat file attachment with the inputs necessary to run the code.

The error is not due to length(). The error is due to having run EDwithNetwork() without providing enough parameters
In particular, you would get that error if you pressed the green Run button to execute EDwithNetwork.
MATLAB never goes looking in the environment for variables that are named in the function() definition.
You should create some code that assigns values to variables that will be used by EDwithNetwork(), and then call the function passing in the appropriate values.

Check this in the command window:
which length
If by mistake any variable or M-file was called by length, the variable can be removed with:
clearvars length
If a mistkaenly named M-file exists, then it should be deleted.

The CVX toolbox defines its own LENGTH function/method. I would not recommend deleting it.
