Randi - aleslab/Psychtoolbox-3-aleslab-fork GitHub Wiki

i=Randi(n,[dims])
Returns a random integer sample from 1:n. The optional second argument
may be used to specify the size of the returned array of independent
samples. E.g. randi(100,[3,3]) returns a 3x3 array of independent samples
drawn from the range 1:100. Also see RAND, RANDN, RandSample, Sample, and
Shuffle.

We assume that n is a positive integer, and rely on the fact that RAND
never returns 0 or 1.

Randi(n) is similar to David Brainard's Ranint(n).
