RANDINT_TEST:
  MATLAB version
  Test the MATLAB RANDINT function.

RANDINT_TEST01:
  In MATLAB, random integers are generated by calling RANDINT:
  If a range is not specified, the values are 0 or 1.

  A = randint ( )      a random scalar value.
  B = randint ( 5, 1 ) a random column vector of 5 entries.
  C = randint ( 1, 5 ) a random row vector of 5 entries.
  D = randint ( 3, 4 ) a 3 by 4 random matrix.
  E = randint ( 5 )    a 5 by 5 random matrix.

a =

     1


b =

     1
     0

     1


c =

     1     1     0     0     0


d =

     0     1     0     1
     0     1     0     0
     0     1     1     0


e =

     1     1     0     1     1
     0     1     1     1     1
     1     1     1     0     1
     0     1     1     1     0
     0     0     0     0     0


RANDINT_TEST02:
  RANDINT allows the user to specify the numeric range.

  A = randint (  1, 1, [ 5,    10 ] ) a random scalar value.
  B = randint ( 10, 1, [ 7,     8 ] ) a random column vector of 5 entries.
  C = randint (  1, 5, [ -1,   +1 ] ) a random row vector of 5 entries.
  D = randint (  3, 4, [ -5,   +5 ] ) a 3 by 4 random matrix.
  E = randint (  5, 5, [ 100, 200 ] ) a 5 by 5 random matrix.

RANDINT_TEST03:
  By setting the random number seed, you can control
  how the random number sequence begins.

  The command "rng ( 123456789 )" sets the seed to 123456789.

  Seed has been set to 123456789

  Now generate 5 random values.
  RANDINT(1,1,[1,100]) = 54
  RANDINT(1,1,[1,100]) = 54
  RANDINT(1,1,[1,100]) = 51
  RANDINT(1,1,[1,100]) = 72
  RANDINT(1,1,[1,100]) = 26

  Seed has been reset to 123456789

  Now generate 5 more random values.
  RAND(1,1,[1,100]) = 54
  RAND(1,1,[1,100]) = 54
  RAND(1,1,[1,100]) = 51
  RAND(1,1,[1,100]) = 72
  RAND(1,1,[1,100]) = 26
