plrandd — Random number generator returning a real random number in the range [0,1]
Random number generator returning a real random number in the range [0,1]. The generator is based on the Mersenne Twister. Most languages / compilers provide their own random number generator, and so this is provided purely for convenience and to give a consistent random number generator across all languages supported by PLplot. This is particularly useful for comparing results from the test suite of examples.
Redacted form: plrandd()
This function is used in examples 17,21.
