rand: Create Random Matrices

Description

Create random matrices.

Usage

rand(n = 1, m = n)
randn(n = 1, m = n)
randi(imax, n = 1, m = n)

Arguments

n, m

integers specifying the size of the matrix

imax

integer or pair of integers

Value

• matrices of size n x m resp. a vector of length n

Details

rand(), randn(), randi() create random matrices of size n x m, where the default is square matrices if m is missing.

rand() uses the uniform distribution on ]0, 1[, while randn() uses the normal distribution with mean 0 and standard deviation 1.

randi() generates integers between imax[1] and imax[2] resp. 1 and imax, if imax is a scalar.
