摘要
通过编程,借助于MATLAB中的库函数,将MATLAB中三维作图与二重积分的自变量取值范围只能是矩形区域扩充到一般区域,让MATLAB能真实准确快速地绘制空间曲面图形和更广泛地计算二重积分.
The programs are edited by means of stored func- tions of MATLAB and rectangular region is expanded into general region, which region of independent variable can only be in three-dimensional graphics and two-dimensional integration of MATLAB So space graph can be plotted truly and exactly and two-dimensional integration can be computed in wider area
