... where even shooting to a fitting point fails— the integration interval has to be partitioned by several fitting points with thesolution being matched at each such point. For more details see[1].CITED ... evaluated using information from both points k, k − 1.The FDEs labeled by Ekprovide N equations coupling 2N variables at points k, k − 1.There are M − 1 points, k =2,3, ,M, at which difference ... Sj,nis an N × 2N matrix at each point k. Each interior point thus supplies ablock of N equations coupling 2N corrections to the solution variables at the points k, k − 1.Similarly, the algebraic...
