Considering the field-programmable gate array (FPGA) can be parallel computing and its computing speed is high, the authors chose FPGA to achieve a large number of Vandermonde … WebWe prove that, more generally, any Vandermonde matrix of a large size is badly ill-conditioned unless its knots are more or less equally spaced on or about the circle { x: x = 1 }. The matrices of the DFT are unitary up to scaling and therefore perfectly conditioned. They are defined by a cyclic sequence of knots, equally spaced on that ...
