I copied this directly from the Matlab documentation, put it in a file named "test", then typed the name of that file in the interpreter. Syntax error. Incorrect use of := operator.
myProc:= proc(n)
begin
if n = 1 or n = 0 then
1
else
n * myProc(n - 1)
end_if;
end_proc:
Now what?

share the link of the documentation where you took from

Patrick Powers's answer moved here for consistency:
It's not online. It is in the Matlab documentation for "procedures."
I gave up on writing procedures and wrote a function instead, which worked.

Turns out that you are using MUPAD (to use it type MUPAD in command window) it's different from MATLAB so basically it's (your code) just a function , so if you want to use it in matlab then see https://www.mathworks.com/help/symbolic/convert-mupad-notebooks-to-matlab.html this converts the MUPAD file to valid MATLAB file.
Plus you know how simple it is in matlab , it's just
factorial(n)
But if you want to know the equivalent syntax for your code in MATLAB then:
a = myProc(10) % function call ,this part should be in a separate file or directly used in command window
function a = myProc(n) % function definition ,this part should be in a separate file named myProc.m
if n == 1 || n == 0
a = 1;
else
a = n * myProc(n - 1);
end
end
Note: See function to know how it works.
