Generation of linear distributed pseudo random numbers in the interval -1 ≤ r < 1.

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.
