d1Grid Class Reference

This class contains the grid points of a "d1baseMan". Each grid point is a point in ambient space with a 1-dimensional tangent space and a normal space attached (that is, a "d1GridPt"). More...

Detailed Description

This class contains the grid points of a "d1baseMan". Each grid point is a point in ambient space with a 1-dimensional tangent space and a normal space attached (that is, a "d1GridPt").

Member Function Documentation

d1Grid::d1Grid(int d,int n,int Nodes,int numElts,int m,baseMatrix<d1GridPt> *gridPntsPtr)

This is the explicit constructor for the d1Grid class.

Parameters:

d - a positive integer specifying the dimension of the manifold (in this case, d = 1).

n - a positive integer specifying the ambient dimension.

Nodes - a positive integer specifying the total number of grid points. Should equal (m - 1)*numElts + 1.

numElts - a positive integer specifying the desired number of elements to use to represent the manifold.

m - a positive integer specifying the number of nodes per element. This parameter determines the order of approximation.

gridPntsPtr - a pointer to a "baseMatrix" of "d1GridPt"s. This "baseMatrix" should have size (numElts + 1 x m - 1). The entries in a row plus the first entry in the next row give the grid points for determining one element. The last row is empty except for the first column.

Returns:

a d1Grid object.

d1Grid::d1Grid(const d1smallGrid &init,REAL normTol)

This is a constructor for the d1Grid class. This constructor generates the normal data given the tangent data and base points.

Parameters:

init - a reference to a "d1smallGrid". This data gives all the base points and all the tangent data for the d1Grid.

normTol - a "REAL" value specifying the tolerence on the angle between the tangent and normal data.

Returns:

a d1Grid object.
