i keep getting an error that says "Local function name must be different from the script name." when i try to call a funtion from a different script

i know my funtion works i just dont know how to call if from a different script

clear all

close all

create_array(10,5,1)

function create_array(N,M,row_orient)

if row_orient==1

for i=1:N

for j=1:M

if N==M

x(i,j)= N*(i-1)+j

elseif M-N >=1 | N-M >= 1

x(i,j)=M*(i-1)+j

end

elseif row_orient==0

for i=1:N

for j=1:M

if N==M

x(j,i)= N*(i-1)+j

elseif M-N >=1 | N-M >= 1

x(j,i)=M*(i-1)+j

end

That error message is correct. If you have a function inside a script file, the name of the function must not be the same as the name of the script. This is documented in the Note in the "Syntax for Function Definition" section on this documentation page.

As stated on this other documentation page functions in script files are not normally accessible outside that script file. If you want that function to be accessible one of the following must be true. [I don't think I missed any possibilities, but if I did these are the most common ways to make a function in a file accessible to the Command Window and other files.] The first is probably the easiest.

The function needs to be the main function in a function file (not a script file)
The script file needs to create a function handle to the function
The function file in which it is a local function needs to return a function handle to that local function, or
The function needs to be a method of a class
