Parameters:

Result:	Where the interpolated control points will be placed.
Input:	Points to interpolate at node parameter values.
Size:	Of control polygon.

Returned Value:

void

SvdLeastSqr

(xtra_lib/nure_svd.c:277)

Prototype:

RealType SvdLeastSqr(RealType *A, RealType *x, RealType *b, int NData, int Nx)

Description:

Least square solves A x = b. The vector X is of size Nx, vector b is of size NData and matrix A is of size Nx by NData. Uses singular value decomposition. If A != NULL is SVD decomposition is computed, otherwise (A == NULL) a solution is computed for the given b and is placed in x.

Parameters:

A:	The matrix of size Nx by NData.
x:	The vector of sought solution of size Nx.
b:	The vector of coefficients of size NData.
NData, Nx:	Dimensions of input.

Returned Value:

RealType: The reciprocal of the condition number, if A != NULL, zero otherwise.

Keywords:
