Generating Gaussian Distributed Random Numbers

I want to generate an awk function that generated a Gaussian distributed set of random numbers. I need to implement the thing below in awk. Rnd is just a uniform random number between 0 and 1

## Generating a POSIX random number?

Hi Guys and gals... As you know I am getting to grips with POSIX and hit this stumbling block. Generating two random numbers 0 to 255 POSIXly. Speed in not important hence the 'sleep 1' command. I have done a demo that works, but it sure is ugly! Is there a better way? #!/bin/sh # Random...

## Generating a Random String of 'n' length

Hi, How can I generate a string of random characters (alpha+numeric) of a particular length ? For e.g. for n=5, output = 'kasjf' n=10, output = 'hedbcd902k' Also, please let me know if random (valid) dates could also be generated. Thanks

## Generating Random Number in certain range

Hi there I am trying to generate a random number between 40 and 70 using the shell here is my code so far and it keeps going above 70. all help much appreciated! comp=\$(( RANDOM%70+40 )) echo \$comp

## C Help; generating a random number.

Im new to C, and Im having a hard time getting a random number. In bash, I would do something similar to the following to get a random number; #!/bin/bash seed1=\$RANDOM seed2=\$RANDOM seed3=\$RANDOM SEED=`expr \$seed1 * \$seed2 / \$seed3` echo \${SEED%.*} Now, in online examples...

## Generating random numbers

Hi, I am having trouble with generating random numbers. can this be done with awk? So I have a file that looks like this: 23 30 24 40 26 34 So column1 is start and column2 is end. I want to generate 3 random #'s between start and stop: So the output will look like this: ...

## generating random numbers with hamming distance 4

Hi I want to genrate 10 random 32 bit binary numbers with hamming distance 4 and 8. 11010110010101010101010101010101 11010110010101010100010101010010 if we look carefully at these two binary numbers they differ at 4 places hence hamming distance 4. Now I want to genrate these numbers...
```dlarnv.f(3)							      LAPACK							       dlarnv.f(3)

NAME
dlarnv.f -

SYNOPSIS
Functions/Subroutines
subroutine dlarnv (IDIST, ISEED, N, X)
DLARNV returns a vector of random numbers from a uniform or normal distribution.

Function/Subroutine Documentation
subroutine dlarnv (integerIDIST, integer, dimension( 4 )ISEED, integerN, double precision, dimension( * )X)
DLARNV returns a vector of random numbers from a uniform or normal distribution.

Purpose:

DLARNV returns a vector of n random real numbers from a uniform or
normal distribution.

Parameters:
IDIST

IDIST is INTEGER
Specifies the distribution of the random numbers:
= 1:  uniform (0,1)
= 2:  uniform (-1,1)
= 3:  normal (0,1)

ISEED

ISEED is 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

N is INTEGER
The number of random numbers to be generated.

X

X is DOUBLE PRECISION array, dimension (N)
The generated random numbers.

Further Details:

This routine calls the auxiliary routine DLARUV 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.
