D503 RMINFC: Minimum of a Function of One Variable
A new subroutine subprogram D503 RMINFC
(Minimum of a Function of One Variable) written in Fortran,
which calculates, to a limited specified accuracy, the abscissa of a
single local minimum of a real-valued function 
lying in a
given interval 
, together with the function value at the
minimum, has been submitted to MATHLIB. In addition,
a double-precision version DMINFC is provided on IBM and similar
computers. This subprogram replaces subroutine subprogram
D509 MINVAR which thus becomes obsolete. The old routine will
be left in KERNLIB for a few months and will then be deleted.
G115 VAVLOV: Approximate Vavilov Distribution and its
Inverse
A new subprogram package G115 VAVLOV
(Approximate Vavilov Distribution and its Inverse) written in Fortran,
which calculates approximate values for the Vavilov density function
and the Vavilov distribution function and its inverse (Vavilov random
numbers), has been submitted to MATHLIB.
The routines in this package are much faster, but usually less accurate,
than the corresponding ones in subprogram package G116 VVILOV
(see below). Their accuracy is, however,
considered sufficient for the relevant application in physics.
This subprogram replaces subroutine package
G111 DISVAV with entries DISVAV, DINVAV, COEDIS
and COEDIN which thus becomes obsolete. The old package will
be left in MATHLIB for a few months and will then be deleted.
G116 VVILOV: Vavilov Density and Distribution Functions
A new subprogram package G116 VVILOV
(Vavilov Density and Distribution Functions) written in Fortran,
which calculates the Vavilov density and distribution functions, has
been submitted to MATHLIB. The routines in this package are much
slower, but usually more accurate, than the corresponding ones in
subprogram package G115 VAVLOV (see above).
