how to load .m funtion to my code?

Hey,

I have a simple question.

when I use functions in C , I need to write the declarations above the main and the functions with their content I write below the main.

In my homework we need to write the functions as a new blablabla.m file.

I noticed that when I am writing a code, assume the file name is question.m , so I actually need to drag the function.m file into the "current folder" window in matlab - but only if I actually drag it!

I dont undersrand why, since they are in the same folder so why it cant recognize it?

So, my question is actually , how can I ensure that the person who will check my hw will load it when he checks the code? is there a way to load it by a command , if it is in the same folder? because I tried the "load" command while the code and the function had been in the same folder and it didnt work.

it worked only when I dragged it.

Thank you :)

I'm not 100% certain I understand the problem you're experiencing, but my guess is that you have a script file foo that defines some variables

% This is foo.m
x = 1;
y = 2;
z = 42;

and a script or function baz that uses those variables.

% baz.m
w = x + y*z;

If this is the case, you need to run foo before running baz. One way to do this is to have baz itself run foo.

% baz.m (modified)
foo
w = x + y*z;

If baz is a function:

function w = baz
w = x + y*z;

you'd need to create the variables inside the function itself:

function w = baz
foo
w = x + y*z;

or you need to tell the user of baz to run the script and pass the variables into baz.

function w = baz(x, y, z)
% To run baz.m you need to create x, y, and z
% One way to create these variables is to run the script foo
%
% Example:
%
% foo
% w = baz(x, y, z)
w = x + y*z;
