Function Documentation

function Xdel = delzerocolumns	(		X,
			epsilon,
			A
	)

function deleting zero-columns from matrix X.

Detection by \(norm^2<\varepsilon\). Optionally, the inner-product-matrix A can be additionally passed for correct computation of the inner product.

Parameters

X	matrix whose zero columns shall be eliminated
epsilon	tolerance value \(\varepsilon\)
A	optional inner product matrix used for norm computation (Default: \(1\))

Return values

Xdel	matrix whose zero columns are deleted
