NAME
CLARNV - return a vector of n random complex numbers from a uniform or normal distribution
SYNOPSIS
SUBROUTINE CLARNV( IDIST, ISEED, N, X )
INTEGER IDIST, N
INTEGER ISEED( 4 )
COMPLEX X( * )
PURPOSE
CLARNV returns a vector of n random complex numbers from a uniform or normal distribution.
ARGUMENTS
IDIST (input) INTEGER
Specifies the distribution of the random numbers:
= 1: real and imaginary parts each uniform (0,1)
= 2: real and imaginary parts each uniform (-1,1)
= 3: real and imaginary parts each normal (0,1)
= 4: uniformly distributed on the disc abs(z) < 1
= 5: uniformly distributed on the circle abs(z) = 1
ISEED (input/output) INTEGER array, dimension (4)
On entry, the seed of the random number generator; the array elements must be between 0 and 4095, and ISEED(4) must be odd. On
exit, the seed is updated.
N (input) INTEGER
The number of random numbers to be generated.
X (output) COMPLEX array, dimension (N)
The generated random numbers.
FURTHER DETAILS
This routine calls the auxiliary routine SLARUV to generate random real numbers from a uniform (0,1) distribution, in batches of up to 128
using vectorisable code. The Box-Muller method is used to transform numbers from a uniform to a normal distribution.

Hi,
What is installation package and how to create it?
When we run:
in AIX:
installp package1
or
in Linux
rpm -ivh mypackage
What is package1 or mypackage in the abov examples and how to create them and deploy them?
I hope my question is clear enough.
Thank you (2 Replies)
What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

After the success of the jq - tool for parsing and manipulating JSON-Data someone wrote a tool called yq, which aims to be the same for YAML, what jq is for JSON. Seems to work fine. I'll definitely give it a chance in future.
