| typedef RandomNumberGenerator RandomTT800 |
Shorthand for the TT800 random number generator class.
| typedef RandomNumberGenerator<detail::RandomState<detail::MT19937> > RandomMT19937 |
Shorthand for the MT19937 random number generator class.
| RandomTT800& vigra::randomTT800 | ( | ) |
Access the global (program-wide) instance of the TT800 random number generator.
| RandomMT19937& vigra::randomMT19937 | ( | ) |
Access the global (program-wide) instance of the MT19937 random number generator.
| double normal | ( | ) | const [inherited] |
Return a standard normal variate (Gaussian) random number.
Mean is zero, standard deviation is 1.0. It uses the polar form of the Box-Muller transform.
