Generation of linear distributed pseudo random numbers in the interval -1 <= r < 1.
- Usage 1
- rand
- Result 1
- Returns a pseudo random number.
- Usage 2
rand(seed {, nr {, nc}})- seed
- if this value is not equal 0, it is used to initialize the random number generator
- nr
- number of rows of the result (default=1)
- nc
- number of columns of the result (default=1)
- Result 2
- A numeric object r with nr rows and nc columns. Each element of r is set to a linear distributed pseudo random numbers in the interval
-1 <= r < 1.
