Why does it appear "Error: Function definitions are not permitted in this context" when I run the following function file?

I have two files for running:

The first one is a script I named preambulo.m which runs ok. The second one is a function which I named final_project_mc.m, when I run this file, it appears the error that I mentioned in the initial question, and I don't know why this is happening. In order to do this exercise you need to run first preambulo.m and then final_project_mc. M.

I would really appreciate any help with this problem.

As the error says, you can't directly execute an m-file which defines a function; you Call the function from a script or another function.

To call the function you would simply incorporate the line

final_project_mc(b)

at the end of the script which would return the output array at the command line as the default variable ans or assign it to a variable as

end_result = final_project_mc(b);

See

doc function % for more details

and section on programming for how scripts and functions work in the "Getting Started" section.

I want to thank you for taking part of your time to answer my question, but I still can´t solve the error. I´m attatching again the files, and putting here the code I used for the file final_project_mc.m (it is already defined as a function not as a script file).

Thank you again for your time.

Code in final_project_mc.m

function output = final_project_mc(b)
global D Y Ym X1 X2 X3 X4 X5 Z theta1
...[bulk of code elided for brevity; _what_ is in the function
   is immaterial to the problem; it's the organization and 
   referencing of the function that is the issue]...dpb
lf_theta_0(:,j),sigm0)).^(1.-D).*1/100;
end
output = -sum(log(out1));
end

But you marked it as solved. I almost didn't look at it but I wanted to add my answer below.

The thing is that the error is not in the file you're showing; it looks fine to me.

Somewhere, though, you have the problem both IA and I have described--we needs must see the actual lines being executed at the command line and the resulting error in context to be able to see precisely where it is; all we have is the symptom but not the root place it occurred. Or, perhaps, the file you're attaching isn't actually the one being referenced but another that is aliasing the one you think you're using.
