The B-Spline FEM is an effective numerical computation method for solving 2-D electromagnetic field problem of rectangular regions.This method has high computational accuracy without destroying the continuity of adjacent field value.In this paper
a transferable Gauss integral matrix algorithm(TGIMA)which can perform fleetly the B-spline FEM was proposed.By the algorithm
the B-spline function value of every Gauss point was transferred to general coefficient matrix of B-spline FEM equation without integral operations of product of B-spline subinterval function.Consequently the computational complexity can be largely reduced.The algorithm can be programmed conveniently and make the computation easier.
