Hi, i'm doing a project for my university.

In a part of it i need to show in a edit text a json file(i don't have to show the structure create by matlab, but only the text of the json file), for example {"Tot_ricoveri":21555,"Rimborsi":[{"Cod_drg":4,"nricoveri_drg":15,"Tot_rimborso_drg":93883.842129455079},.....

The problem is: how can i read this file?

I tryed with this:

fname1 = 'OSPEDALE6_ASL_GLUCOSIO_REGIONE2.json';

fid = fopen(fname1,'r');

fclose(fid);

set(handles.JSON,'String',fid)

But it, print 5 and not what i want.

Have you read the documentation? It is a great place to start.

It will tell you that the fid is a handle to a file, not its contents. You need to use any of the several functions linked at the bottom of the doc page for fopen.

You could even use the fileread function instead.
