opt::CommE04WB::setter_centraldiff-interval

 Contents

1 Description

If the algorithm switches to central differences because the forward-difference approximation is not sufficiently accurate, the value of r is used as the difference interval for every element of x
Used by: centraldiff-interval in e04ucf and e04uff (no CPP interface).
CommE04WB::setter_centraldiff-interval returns a reference to the communication class itself.
