By using the adaptive steplength integration scheme with a shooting technique, a rather difficult singular perturbation problem
of ordinary differential equations with boundary layers can be calculated effectively. Computing examples are given in this
paper which show the convergence within one iteration of the method in the case of a linear problem, the efficiency of the
method for many boundary layers and turning points, especially the convenience in calculating multiple solutions. A comparison
with traditional difference method is given at the end of this paper. 相似文献

用自适应步长积分格式结合打靶技巧,可以有效地求解比较困难的常微分方程边界层型奇异摄动问题.本文给出了若干计算实例,说明了这种方法应用于线性问题时的一次收敛性,以及应用于单端、双端边界层、转向点和多个边界层时的效果,特别是能方便地求出多解.最后并与习用的差分方法作了比较. 相似文献
