Function error | Error: Function definitions are not permitted at the prompt or in scripts.

Hello everybody,
I'm a new member of this community. I'd appreciate your help for a problem that I'm having with a little, silly function whom I type the code here.
function [val_min, pos_min] = comparison1(Isole_mat,Elhierro_mat)
[r,c]=size(Isole_mat);
for i = 1:r
latP = Isole_mat(i,2);
lonP = Isole_mat(i,3);
diffLat = latP - Elhierro_mat(:,2);
diffLon = lonP - Elhierro_mat(:,3);
distanza(:,i) = diffLat.^2+diffLon.^2;
%[dmin, I] = min(distanza(:));
end
[val_min, pos_min] = min(distanza);
What's wrong with it? Why do I get always the error message | Error: Function definitions are not permitted at the prompt or in scripts.
I saved the function in a m.file within the same name...
Please, help me understand.
Thank you in advance!

Please check that in your comparison1.m file, that the only lines before the "function" line, are comment lines and blank lines.

Do you have more than one m-file with the name, comparison1? Check with
which comparison1 -all
Is
function [val_min, pos_min] = comparison1(Isole_mat,Elhierro_mat)
.
the first line in the m-file? And is
end
.
the last line of the m-file? The "end", which match "function" is optional, but I think it makes the function easier to read.
The Code Analyzer box (or mlint-box) at the right top of the editor is it green or at least not red?
