How do I fix my MATLAB? It won't save my m file now for some reason.

I am trying to save some code on my laptop. But when I try to save it, every time I put in the folder I want it doesn't save anything. So it never renames the m file. It leaves it as 'Untitled*'

My code is below:

%This is project 3.2 from "Numerical and ANalytical Methods with Matlab" %Date: 6-9-18 %Done by Joshua Tashbar

clear; clc;

%This makes a A matrix of zeroes 18 by 18 matrix;

A=zeros(18);

%This creates a zeroes column vector 18 rows by 1 column;

P=zeros(18,1);

%Note: all forces are in kN

%This is the reaction at F, where the truss is leaning against the wall.

Fx=((5*6)+(5*12)+(5*18)+(15*8)+(15*16))/12;

%This is the reaction at the pin support at point A in the x-direction

Ax=15-Fx;

%This is the reaction at the pin support at point A in the y-direction

Ay=30;

%This defines the angle theta in degrees

Please any help will be greatly appreciated. Thanks

So when you hit save and it brings up the save dialog box starting in the current folder, and you type in some name other than "untitled.m", what does it do? Does it just go away as if it thought everything saved just fine? Or does it throw an error message, like maybe with something about permission for save in that folder?

Yes, it just goes away as if it thought everything saved just fine but in matlab it still continues to say 'Untitled*' No error messages.

Are you sure you didn't say "save copy as" instead of "save as"?

Yeah. I'm sure; I think it wans't saving because I was naming the m file the same name as the folder it was supposed to go in. But now its saving which is good. Thanks for your help.
