A combination focuses on the selection of objects without regard to the order in which they are selected. This algorithm (program in Matlab) calculates the number of permutations and combinations of N objects taken D at a time. Yeah, I agree with what has just been said. Number of all permutations of n things, taken r at a time, is given by n P r = \mathbf{\frac{n!}{(n-r)!}} P = perms(v) returns a matrix containing all permutations of the elements of vector v in reverse lexicographic order.Each row of P contains a different permutation of the n elements in v.Matrix P has the same data type as v, and it has n!

Permutation is an arrangement of objects in a definite order. I can barely wait to buy this program now. GRE Math Help » Arithmetic » Permutation / Combination Example Question #1 : Permutation / Combination. The sequence of numbers produced by randperm is determined by the internal settings of the uniform pseudorandom number generator that underlies rand, randi, randn, and randperm.To control that shared random number generator, use the rng function. Many permutations can be derived from a single combination. There is a set of numbers such as [1 0 1 0 1 1], and now I need to flip two of them arbitrarily, such as flipping the first and the second, then the result is [0 1 1 0 1 1], I need to enumerate all flipped result. P = perms(v) returns a matrix containing all permutations of the elements of vector v in reverse lexicographic order.Each row of P contains a different permutation of the n elements in v.Matrix P has the same data type as v, and it has n! For example, if we have two elements A and B, then there are two possible arrangements, AB and BA. Permutation : It is the different arrangements of a given number of elements taken one by one, or some, or all at a time. Combinations: Each of the different groups or selections which can be formed by taking some or all of a number of objects is called a combination.
