I thought its not important. Yeah I typed

path

I have found the parent Directory for Class there. So why still this is a problem ?

Thanks :)

Yeah I got it. The main problem is that the class was on another path. So I import the data, then it is saved to uint32 then I run the class.

So it was sorted out using the following: 1- Add path by either manually (addpath command) or by running the class file 2- Load the .mat file

But every time I run the file, I should add the path, how to add path permanently ?

 how to add path permanently
addpath D:\MFiles\YourFolder -end
savepath

Look in the documentation of addpath: https://www.mathworks.com/help/matlab/ref/addpath.html. At the bottom you find the "See also" line, which contains useful related commands. Here the gem savepath is mentioned.

Alternatively you can do this using the pathtool: Select the folder in a GUI and save the path permanently.

Sometimes there are problems saving the path, if the user does not work with admin privileges (but this is a good idea!). Then writing to matlabroot\toolbox\local\pathdef.m does not work. I solve this by allowing users to modify this file in the Window Explorer.
