WebApr 14, 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. http://www.ece.northwestern.edu/local-apps/matlabhelp/techdoc/ref/inv.html
