What is Randi in Matlab?

X = randi( r , n ) creates an n -by- n codistributed matrix of uniformly distributed random integers in the range defined by r . If r is a scalar, the function creates random integers in the range 1 to r . If r is a vector, the function creates random integers in the range r(1) to r(2) .

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 .

What does Randn do in Matlab?

By default, randn(n,"like",1i) generates random numbers from the standard complex normal distribution. The real and imaginary parts are independent normally distributed random variables with mean 0 and variance 1/2 .

How do you create a random number matrix in Matlab?

You can use the randperm function to create a double array of random integer values that have no repeated values. For example, r4 = randperm(15,5);
