RandomIntMatrix

Returns a matrix with random integer entries.

Syntax

• RandomIntMatrix(n[, m], A, B)

  • n and m are positive integers

  • A and B are integers with B > A

Description

RandomIntMatrix(n, m, A, B) returns a matrix of size n×m in which each entry is a random integer in [A, B) ∩ ℤ. If omitted, m defaults to n, thus creating a square matrix.

Examples

mean(compute(RandomIntMatrix(5, 0, 10), n, 1, 1000000))
