Name

ranl_normal − Routine to generate normally distributed random numbers using summation of uniformly distributed random numbers

FORMAT

RANL_NORMAL (s1, s2, nsum vnormal, n)

Arguments

s1integer∗4
On entry, s1>=1, the first part of the two-integer seed. 
On exit, s1 is changed according to n∗nsum steps of the L’Ecuyer method. 

s2integer∗4
On entry, s2>=1, the second part of the two-integer seed. 
On exit, s2 is changed according to n∗nsum steps of the L’Ecuyer method. 

nsuminteger∗4
On entry, the number of uniform[0,1] numbers to sum to get each N(0,1) output.

vnormalinteger∗4
On exit, a vector vnormal(1),...,vnormal(n) of N(0,1) normally distributed numbers. 

ninteger∗4
On entry, n>=1 specifies the number of N(0,1) results to return in vnormal(1),...,vnormal(n). 

Description

The RANL_NORMAL routine returns a vector of N(0,1) normally distributed random numbers. 

For parallel applications using the RANL_NORMAL routine, DXML provides two auxiliary, input programs.  Refer to the descriptions of RANL_SKIP64 and RANL_SKIP2. 

Example

See the example for RANL_SKIP64.
