Error: No such file or directory

So, i have a function called 'MatrixPicture', which uses data that is PMHFIB_ORIGINAL.ATT. file. To open the .att file, I'm using a secondary function called 'Read_Att2'. However, when I call on the .att file, I get the message: "no such file or directory found."

Below, is my code for my MatrixPicture function that is calling on Read_Att2. How do I fix this issue? Read_Att2 is located in the folder on the desktop known as PHYS4115Mfiles, while PMHFIB_ORIGINAL.ATT is located in PHYS4115Tables on my desktop. I am on Mac Book air.

function [t,EIS] = MatrixPicture (min,max,m,n)
drive_name ='/Users/kira/desktop/';
addpath '/Users/kira/desktop/PHYS4115Mfiles';
filename ='C:\User\kira\desktop\PHYS4115Tables\att\PMHFIB_original.ATT';
%flux is temp variable
[E,mewfib]=Read_Att2([drive_name,'\PHYS4115Tables\att\PMHFIB_ORIGINAL.ATT']);

Two comments

• you are mixing \ and / as file separator.
• you use relative paths, thus the current directory is important.

/ never used a MacOS

[Walter Roberson]

MS Windows recognizes both \ and / as path separators, but Mac and Linux only recognize / as path separators and treat \ as the escape character sequence (for example \n would be "newline")

[per isakson]

Either

addpath('/Users/kira/desktop/PHYS4115Mfiles');  % with blips

or

addpath /Users/kira/desktop/PHYS4115Mfiles     % without blips

As outside people who have never seen your computer, we have no reason to expect that a file with the exact name FracturesNoisy.mat is anywhere on your MATLAB path.

I suggest you

ls Fract*

to see what names are available in your current directory

Hi guys.

If anyone has trouble saving a .mat file and keps seeing the error 'no such file or directory exists', please try the following:

on the matlab Home tab, under variables, you will see 'save worspace' and 'clear workspace'

click on save workspace, and then pick the name of your file.

Matlab will now recognise the file and folder, and you can do whatever you want to do with the said file later on.

if this works for you too, please let me know as I really struggled for days with this
