Undefined function or variable 'anualanomalie'

I have a function that gives the average of 136 values that are in a column of a text file (Image 2) and I want to show that average to the user in the command window.

But when I run the program it says: "Undefined function or variable 'anualanomalie'. " (Image 1)

Also, load1 is another function (Image 3).

What can I do? Where is the problem? Thanks

When you call a function that has outputs, you need to store the outputs into variables if you want to use them. A syntax such as

function [A, B] = testfunction

does not result in A and B being stored in the caller: it tells MATLAB to use A and B to "stand in" for whatever output variables that the user is assigning the values to.

We recommend that you do not use "sum" as the name of a variable: you will almost certainly eventually try to use sum() as a function in the same routine that you used sum as a variable.
