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.
