PetscRandomSetInterval#
Sets the interval over which the random numbers will be distributed. By default, this interval is [0,1).
Synopsis#
#include "petscsys.h"
PetscErrorCode PetscRandomSetInterval(PetscRandom r, PetscScalar low, PetscScalar high)
Not Collective
Input Parameters#
r - the random number generator context
low - The lower bound of the interval
high - The upper bound of the interval
Notes#
for complex numbers either the real part or the imaginary part of high must be greater than its low part; or both of them can be greater.
If the real or imaginary part of low and high are the same then that value is always returned in the real or imaginary part.
