UNPR

This function evaluates the uniform probability density function.

Function Return Value

UNPR — Function value, the value of the probability density function. (Output)

Required Arguments

X — Argument for which the uniform probability density function is to be evaluated. (Input)

A — Location parameter of the uniform probability function. (Input)

B — Value used to compute the scale parameter (B ‑ A) of the uniform probability density function. (Input)

FORTRAN 90 Interface

Generic: UNPR (X, A, B)

Specific: The specific interface names are S_UNPR and D_UNPR.

FORTRAN 77 Interface

Single: UNPR (X, A, B)

Double: The double precision name is DUNPR.

Description

The function UNPR evaluates the uniform probability density function with location parameter A and scale parameter (B ‑ A), defined

 

Example

In this example, we evaluate the uniform probability density function at X = 0.65, A = 0.25,
B = 0.75.

 

USE UMACH_INT

USE UNPR_INT

IMPLICIT NONE

INTEGER NOUT

REAL X, A, B, PR

CALL UMACH(2, NOUT)

X = 0.65

A = 0.25

B = 0.75

PR = UNPR(X, A, B)

WRITE (NOUT, 99999) X, A, B, PR

99999 FORMAT (' UNPR(', F4.2, ', ', F4.2, ', ', F4.2, ') = ', F6.4)

END

Output

 

UNPR(0.65, 0.25, 0.75) = 2.0000
