int rand_range	(	int	nr,
		double *	d,
		double	low,
		double	up,
		int	type
	)

Fills the double array with random numbers between specified limits. Set seed for random number generator before calling this routine, for example with srand(time(NULL));

Returns:

Returns 0 when successful, otherwise <> 0.

Parameters:

nr	Nr of values in double array
d	Pointer to allocated double array
low	Lower limit for random values
up	Upper limit for random values
type	Distribution: 0=even, 1=square-root transformation
