Hello,
could someone write what is the difference between possible location of the "end" statement of the main function: before first local function vs end of a file? What is the difference?
Thank you!
Marek

"before first local function"
any functions defined after the main function are local functions:
"vs end of a file?"
any functions defined within the main function are nested functions:
These can be combined too, e.g.:
function mymain()
... code
function mynest()
... code
end % mynest()
end % mymain()
function mylocal()
... code
end % mylocal()
Nested functions have access to the parent function's workspace. Local functions do not.

function caller
a = 1;
function c = foo(d)
eval('b = d;'); % error "forbidden"
c = a + b;
end
function c = bar(d)
b = [];
eval('b = d;'); % OK
c = a + b;
end
fprintf('bar(2) = %g\n', bar(2));
fprintf('foo(2) = %g\n', foo(2)); % this won't run
end
