function i=Randi(n,dims) % 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). % Denis Pelli 4/19/96, 6/25/96, 6/29/96, 7/22/97 % 7/24/04 awi Cosmetic % 1/29/05 dgp Changed default dims from 1 to [1 1]. % 7/21/11 mk Fix bug in arg checking, as reported by Todd Horowitz. if nargin<1 || nargin>2 || numel(n)~=1 error('Usage: i=Randi(n,[dims])') end if nargin==1 dims=[1 1]; end i=ceil(n*rand(dims));
