- %RAND Uniformly distributed random numbers and matrices.
- % RAND(N) is an N-by-N matrix with random entries, ordinarily
- % chosen from a uniform distribution on the interval (0.0,1.0).
- % RAND(M,N) or RAND([M,N]) is an M-by-N matrix with random entries.
- % RAND(SIZE(A)) is the same size as A.
- % RAND with no arguments is a scalar whose value changes each time
- % it is referenced.
- %
- % RAND('seed') returns the current seed of the uniform generator.
- % RAND('seed',s) sets the uniform generator seed to s.
- % RAND('seed',0) resets the seed its startup value.
- % RAND('seed',sum(100*clock)) sets it to a different value each time.
- %
- % By default, RAND samples a uniform distribution. The function
- % RANDN generates normally distributed random matrices.
- % RAND and RANDN have separate generators, each with its own seed.
- %
- % Previous versions of MATLAB allowed RAND('normal') to switch
- % the prevailing distribution to normal, RAND('uniform') to switch
- % back to uniform distribution, and RAND('dist') to return a string
- % containing the prevailing distribution, either 'uniform' or 'normal'.
- % MATLAB Version 4.0 continues to allow this switch, but
- % issues a warning message discouraging its use.
