# sc\_RedundantCartesianSubIter(3)

Like RedundantCartesianIter, except a, b, and c are fixed to a given value.

## NAME

sc::RedundantCartesianSubIter - Like **RedundantCartesianIter**, except a, b, and c are fixed to a given value.

## SYNOPSIS

`#include <cartiter.h>`

Inherited by **sc::RedundantCartesianSubIterCCA**, **sc::RedundantCartesianSubIterCints**, and **sc::RedundantCartesianSubIterV3**.

### Public Member Functions

 Returns **a()** if i==0, **b()** if i==1, and **c()** if i==2.  int **axis** (int i)\
 Return the i'th axis.

## Detailed Description

Like **RedundantCartesianIter**, except a, b, and c are fixed to a given value.

## Member Function Documentation

### virtual int sc::RedundantCartesianSubIter::bfn ()` [pure virtual]`

Return the current Cartesian basis function number.

Implemented in **sc::RedundantCartesianSubIterCints**, **sc::RedundantCartesianSubIterCCA**, and **sc::RedundantCartesianSubIterV3**.

### void sc::RedundantCartesianSubIter::start (int a, int b, int c)

Initialize the iterator. The constraints on a, b, and c are given as arguments.
