The randi function returns double integer values drawn from a discrete uniform distribution. For example, r2 = randi(10,1000,1); r2 is a 1000-by-1 column vector containing integer values drawn from a discrete uniform distribution whose range is in the close interval [1, 10].

How to use Randi in an array Matlab?
X = randi( imax , sz ) returns an array where size vector sz defines size(X) . For example, randi(10,[3 4]) returns a 3-by-4 array of pseudorandom integers between 1 and 10. X = randi(___, typename ) returns an array of pseudorandom integers between 1 and imax of data type typename .
How do you generate a random number within a range in Matlab?
Use the rand function to draw the values from a uniform distribution in the open interval, (50,100). a = 50; b = 100; r = (b-a). *rand(1000,1) + a; Verify the values in r are within the specified range.
What is random integer in Matlab?
This example shows how to create an array of random integer values that are drawn from a discrete uniform distribution on the set of numbers –10, –9,...,9, 10. The simplest randi syntax returns double-precision integer values between 1 and a specified value, imax .
How do you pick a random number from an array in Matlab?
A=A_index(randperm(length(A_index),1));
