WebMy earlier link gives a derivation of the 4th order 9-point compact stencil for a 2D Cartesian Poisson equation with a non-constant inhomogeneous term. Cite 2 Recommendations WebOct 20, 2012 · As part of my project I need to solve a quartic polynomial in a closed form in C++. A*x 4 + B*x 3 + C*x 2 + D*x + E = 0. I found several links to this end. One of them is here. But it computes all roots, while I want just real roots. The algorithms mainly use Ferrari's method to reduce the order. bool solveQuartic (double a, double b, double c ...
