The implicit compact finite-difference scheme was developed for evolutionarypartial differential parabolic and Schr\"odinger-type equations and systemswith a weak nonlinearity. To make a temporal step of the compact implicitscheme we need to solve a non-linear system. We use for this step a simpleexplicit difference scheme and then Newton -- Raphson iterations, which areimplemented by the double-sweep method. Numerical experiments confirm the 4-thorder of an algorithm. The Richardson extrapolation improves it up to the 6-thorder.
