Gaussian elimination with a choice of main element throughout the matrix (the full scheme of choice). This scheme allowed violation of the natural order exception unknown.On step 1 mtoda among the elements aij define maximum element modulo ai1j1. The first equation and the equation systems with number i1 swap. Further, the standard way to produce an exception unknown xi1 from all equations, except the first.At the k-th step of the method among the coefficients aij (k-1) in the equations in the unknown system with numbers i = k, ..., n choose maximum modulo aikjk coefficient (k-1). Then the k-th equation and equation containing the found ratio, swap and exclude unknown xjk of equations with numbers i = k + 1, ..., n.Reverse phase unknown calculate as follows: xjn xjn,-1, ..., xj1.
