gsGridIterator< T, CWISE, d, false > Class Template Reference

Detailed Description

template<class T, short_t d>
class gismo::gsGridIterator< T, CWISE, d, false >

Iterator over a Cartesian product of points, which is given by coordinate-wise point sets.

The iteration is done in lexicographic order. Usage:

gsGridIterator<T,CWISE> grid(a,b);

or

gsGridIterator<T,CWISE,d> grid(a,b);

Template Parameters

T	type of the numeric coordinates of the index vector
d	statically known dimension, or dynamic dimension if d = -1 (default value)

Constructor & Destructor Documentation

gsGridIterator ( const CwiseContainer &  cwise )

inlineexplicit

Constructor using references to the coordinate vectors.

Parameters

cwise

A container of matrices or vectors, each containing the sample points in the respective coordinate

Member Function Documentation

const gsMatrix<T> operator[] ( const point_index &  ti ) const

inline

Returns the point corresponding to tensor index ti.

Note

Unlikely to std iterators, the position is not counted from the current position of this, but from the starting point of the iteration

Parameters

ti	a valid tensor index of a point in the iteration sequence
