DFZERO

 
Finds zero of REAL FUNCTION F(X) on interval [B,C] to relative and absolute
accuracy RE, AE. Requires EXTERNAL statement for user selected function name. R
is input estimate of location of zero, if this is known. Best output estimate of
zero returned in B.
 
Classes  :  F1b . Solution of single general nonlinear equations
 
Type     : Fortran software in NMS collection.
