I have a problem when opening Matlab window

When opening MATLAB window I get a problem that MATLAB window showing signs like this: > In matlabrc (line 158)

Did you mean: >> a=mean(X); Undefined function or variable 'mean'.

How can I solve this problem?

It appears that you have created a script called 'feature' (C:\Users\abapihi\Documents\MATLAB\feature.m).

feature is a built-in Matlab function and Matlab is attempting to call it during startup, but instead it sees your script.

You should rename your script file to avoid this conflict.

A general rule is to avoid naming your own scripts or functions with names that are already used by Matlab. Use the command "which commandname" to check if commandname is already defined/used.
