I'm now learnign to use MatLab and I'm not sure where I went wrong.

function ave=myaverage(x,N)
sizex=size(x);
sizeN=size(N);
   if sizex(2)>sizeN(2)
       beep
       disp('Error')
   else 
       total=sum(N);
       s=x.*N;
       ave=sum(s)/total
   end
end

I encounter several errors when creating the finction:

The function "myaverage" may be unused
unable todefine the local function "myaverage" because it has the same name as the file.

Also when calling the function, i encountered as error:

i. Function with duplicate name "myaverage" cannot be defined.

在 MATLAB Online 中打开

In MATLAB a file containing function definition cannot contain any other line of code before

function ...........

so remove the line

clc; clear all

from the top of the file myaverage.m. It confuses the MATLAB; this innocent-looking line causes both errors and the warning. Remove it, and all the errors will be resolved
