randintrlv

Reorder symbols using random permutation

Syntax

intrlvd = randintrlv(data,state)

Description

intrlvd = randintrlv(data,state) rearranges the elements in data using a random permutation. The state parameter initializes the random number generator that the function uses to determine the permutation. state is either a scalar or a 35x1 vector, and is described in the rand function, which is used in randintrlv. The function is predictable and invertible for a given state, but different states produce different permutations. If data is a matrix with multiple rows and columns, the function processes the columns independently.

This function uses, by default, the Mersenne Twister algorithm by Nishimura and Matsumoto.

    Note:   Using the state parameter causes this function to switch random generators to use the 'state' algorithm of therand function.

    See rand for details on the generator algorithm.

Examples

For an example using random interleaving and deinterleaving, see Improve Error Rate Using Block Interleaving in MATLAB.
