Francesco, with xlsread you read the entire spreadsheet. Which means, that you can read an entire matrix as is, at once. E.g., from the MathWorks documentation:

 values = {1, 2, 3; 4, 5, 6; 7, 8, 9};         % write matrix to .xlsx file
 headers = {'First','Second','Third'};
 xlswrite('myExample.xlsx', [headers; values]);

and then

 filename = 'myExample.xlsx';                   % read matrix from file
 A = xlsread(filename)
     1     2     3
     4     5     6
     7     8     9

as expected, A is read as a 3-by-3 matrix.
