Generation of gaussian distributed pseudo random numbers.
- Usage
grand(m {, s , seed , nr , nc})
- m
- mean value of the gaussian distribution
- s
- standard deviation of the gaussian distibution (default=1)
- seed
- if this value is not equal 0, it is used to initialize the random number generator (default=0)
- nr
- number of rows of the result (default=1)
- nc
- number of columns of the result (default=1)
