Description
The routine ?larnd returns a random number from a uniform or normal distribution.
Input Parameters
- idist
-
INTEGER. Specifies the distribution of the random numbers. For slarnd and dlanrd:
= 1: uniform (0,1)
= 2: uniform (-1,1)
= 3: normal (0,1).
For clarnd and zlanrd:
= 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
-
INTEGER. Array, size 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.
Output Parameters
- iseed
-
INTEGER.
On exit, the seed is updated.
- res
-
REAL for slarnd,
DOUBLE PRECISION for dlarnd,
COMPLEX for clarnd,
DOUBLE COMPLEX for zlarnd,
Random number.
