Least-Squares optimal affine subspace

No BSD License

Computes the affine subspace (eg, line, plane) that optimally fits the input data

File Information
Description	The zip includes: (1) lsqAffineSpace: a 'low level' routine that takes a set of m-dimensional real sample data and returns the optimal-fit k-dimensional affine subspace, with some options for discarding outliers. (2) lsqPlane and lsqLine: lsqAffineSpace wrappers, that compute optimal line and hyperplane (plane, if the samples are 3-vectors) of the input samples. (3) lsqAffineTestScript: demonstrating usage of the functions.
MATLAB release	MATLAB 7.2 (R2006a)

Other Files	lsqAffineSpace.m, lsqAffineTestScript.m, lsqLine.m, lsqPlane.m
