DQ1DA

 
Adaptive quadrature to estimate integral from A to B to accuracy EPS of REAL
FUNCTION F(X). Returns error estimate in E and number of integrand evaluations in
KF. Does not require EXTERNAL statement but integrand must be called F.
 
Classes  :  H2a1a1 . Automatic 1-D finite interval quadrature (user need only
                   specify required accuracy), integrand available via
                   user-defined procedure
 
Type     : Fortran software in NMS collection.
Access   : Public domain. Portable.
Precision: Double.
 
Usage    : CALL DQ1DA(A,B,EPS,RESULT,E,KF,IFLAG)
 
Details  : Documentation Fullsource Sample Source
Sites    : (1) ITL
