Let's do an example: I have a file called Pippo.mat To load in matlab I use this function: load('Pippo.mat')
How can I let matlab read Pippo.mat? Thank you.

What's the question exactly?
You want to turn a mat file to csv file?! or ?
Sorry I'm confused
Have a look at
csvwrite()
and
csvread();
to turn the mat files to csv

Please explain the difference between "load" and "read" and where does the conversion appear?

In matlab, to write a table to a csv file, use:
load('YourTableData.mat')
writetable(YourTableData, 'FileName.csv')

Hi Agnese,
Guessing from the title of your question, I think you want to load a MAT file into the MATLAB workspace and convert it to a CSV file, which you want to use it for further processing.
If this is the case, you can follow this workflow. Let's say we have a MAT file 'abc.mat' (attached), which contains two matrices and you want to load the two matrices into MATLAB and create a CSV from the concatenated matrix:
load('abc.mat');
%Concatenate matrices A and B
C = [A, B];
%Write CSV file
csvwrite('test.csv',C);
The created CSV file 'test.csv' is also attached. You can then use 'csvread' if you need to read from the created CSV file. The doc for csvread is here
Hope this helps
Cheers!

Error using csvwrite (line 47)
Cannot open file test.csv.
How can solve it?

You do not have write access to your current directory. You should either cd() to a directory that you do have write access to, or else you should give the path to a location you do have write access to, such as
csvwrite('C:\Users\Yasser\Documents\MATLAB\Project3\test.csv', data_to_write);

Any Idea please ?? Thank you

load() loads .mat files and other data files, not m-files. You cannot do
s = load(Untitled5.m');
to run your m-file, you just click the green Run tool button on the toolbar, or type F5 function key.

Can you attach the file?
Your use of .m as an extension hints the file might be MATLAB code, but you would execute MATLAB code instead of load()'ing it.
