DFMIN

 
Finds minimum of REAL FUNCTION F(X) on interval [AX,BX] to accuracy EPS. Needs
EXTERNAL statement for user selected function name. Returns FMIN as location of
minimum with AX,BX bracketing this value.
 
Classes  :  G1a1a . Unconstrained optimization of a smooth univariate
                  function, user provides no derivatives
 
Type     : Fortran software in NMS collection.
Access   : Public domain. Portable.
Precision: Double.
 
Usage    : R = DFMIN(AX, BX, F, EPS)
