Generation of Random Variates

generates random variates from over 870 univariate distributions

Random derangement

Generate sequences of random derangement

A derangement is a permutation of the elements of a set, such that no element appears in its original position.The code use non rejection method for better predictable runtime.

RANDPERMFULL

RANDPERMFULL (N) returns a random derangement (complete permutation) of the integers from 1 to N

RANDPERMFULL(N) creates a row vector R, such that R(j) ~= j for all j=1:N. This type of permutation is called a derangement.N should be larger than 1.Example:randpermfull(7) % might be [2 4 5 6 1 7 3], but not

output elements. Optional, default: N.OUTPUT: Index: [1:NOut] elements of shuffled [1:N] vector in the smallest possible integer type.3. Derangement index:Index = Shuffle(N, 'derange', NOut)Equivalent to

RPG Lab

A set of functions for generating and testing random permutations of the integers (1,2, ..., n).

The main functions provided are:1. p = GRPfys(n); generates a random permutation of length n.2. p = GRPmex(n); generates a random permutation of length n.3. p = GRDrej(n); generates a derangement of

PARTPERM -- Partial random permutation of a vector

Partial random permutation of a vector.

("derangement"). If you don't like this, use the following syntax: X = PARTPERM(A,IDX,'allow') randomly permutes the elements of vector A which are specified by vector IDX, but allows indexed elements to remain

Generate uniform pseudo-random integers from linear range.

RAND_INT(R,N) returns an n-by-n matrix containing pseudo-random integer values from range R.
