rand

Uniformly distributed random numbers in [0, 1].

Syntax

r = rand
r = rand(n)
r = rand(m, n)
r = rand(d1, d2, d3, ...)

Description

Returns pseudorandom values drawn from the uniform distribution on [0, 1]. With no arguments, returns a single scalar. With dimensions, returns an array of the requested shape. Uses MathJet’s interpreter-shared PRNG state.

Examples

rand                     % e.g. 0.4321
rand(3)                  % 3×3 uniform random matrix
rand(1, 100)             % row vector of 100 samples
