RandomComplex

RandomComplex[]

gives a pseudorandom complex number with real and imaginary parts in the range 0 to 1.

RandomComplex[{zmin,zmax}]

gives a pseudorandom complex number in the rectangle with corners given by the complex numbers zmin and zmax.

RandomComplex[zmax]

gives a pseudorandom complex number in the rectangle whose corners are the origin and zmax.

RandomComplex[range,n]

gives a list of n pseudorandom complex numbers.

RandomComplex[range,{n1,n2,…}]

gives an n1×n2×… array of pseudorandom complex numbers.

Details and Options

  • RandomComplex chooses complex numbers with a uniform probability distribution in the rectangle specified.
  • RandomComplex[range,WorkingPrecision->n] yields complex numbers with n-digit precision. Leading or trailing digits in the generated number can turn out to be 0.
  • RandomComplex gives a different sequence of pseudorandom complex numbers whenever you run the Wolfram Language. You can start with a particular seed using SeedRandom.
  • A Method option to SeedRandom can be given to specify the pseudorandom generator used.
