Rectangular matrix inverse
WebbIn mathematics, and in particular, algebra, a generalized inverse (or, g-inverse) of an element x is an element y that has some properties of an inverse element but not necessarily all of them. The purpose of constructing a generalized inverse of a matrix is to obtain a matrix that can serve as an inverse in some sense for a wider class of matrices … Webbunique solution o af certai n set of equations. This generalized inverse exists for any (possibly rectangular) matrix whatsoever with complex elements J. I t is used here for …

Webb14 apr. 2024 · B = invvander (v, m) returns the pseudoinverse of a rectangular Vandermonde Matrix. v has to be a row vector and v = [x1, x2, ..., xn] while m has to be a scalar and positive integer of the above matrix V. If m equals the number of v, then B is the inversed square Vandermonder matrix. Webbwhere I denotes the unit matrix or identity ma- trix having l's along its principal diagonal and 0's elsewhere.
