Hi SEID

From my understanding of your question I assume you want to create 3*5 matrix of random numbers from 1-10

You can use the 'randi' function ( Uniformly distributed pseudorandom integers ) in folllowing way-

mat = randi(10,3,5)   % 3,5 is the size of the matrix and 10 is the upper range for the matrix elements.

mat = 3×5

8 8 5 10 8 4 1 9 4 8 6 6 10 8 1

If the numbers are supposed to be integers:

A = randi([1 10],3,5)

A = 3×5

9 4 6 9 10 5 6 1 6 6 2 5 4 10 9

otherwise, if the numbers can be any value in the specified interval:

A = rand(3,5)*9+1

A = 3×5

6.1228 3.6624 6.5019 7.3853 1.8787 5.0588 4.5854 1.7705 8.1341 8.7430 3.2489 8.8081 4.4995 4.7077 2.4313
