Come posso fare per scrivere uno scripts matlab che restituisca gli elementi di una matrice in coppia?
Se scrivo A = [1 2 3; 4 5 6; 7 8 9]; crea la matrice ogni volta.
Se scrivo: load ('filename.mat') Error using load
Unable to read file 'Filename.mat'. No such file or directory.
Posso visualizzare la matrice solo se la digito sulla command window

Is your mat file called "filename.mat"? Or do you have the actual name in filename, like
filename = 'abc.mat';
? If filename is one of your variables, try this:
s = load(filename) % Load structure containing all the variables in the .mat file.

OK. Good luck. Write back if you have any questions, and attach your code and .mat file.

Sorry, I forgot to ask you how I write my code. I wrote this code:
A = load('filename.mat');
X = rand(A);
But i have this error: "Error using rand. Size inputs must be numeric."
Why? What is the correct code, to generate a permutation matrix (the matrix above) without repetitions?
