Detailed Description

Interface for Casacore Vectors in least squares fitting.

Review Status

Date Reviewed:

2004/04/01

Prerequisite

• LSQFit class

Etymology

From Least SQuares and aips++ (now Casacore)

Synopsis

The interface used in the LSQaips class is in terms of Casacore Vectors directly, rather than an STL iterator (like VectorSTLIterator ) based on it.

Its functionality is identical to that of the LSQFit class, although it will be faster to use the iterator interface directly, since constructing of temporary iterators can be avoided

Example

See the tLSQaips.cc program for extensive examples. Note: this class is in an interim state.

Motivation

The class was written to enable easy tranistion from the current Vector to the Vector::iterator interface.

To Do

• create all the method interfaces
