当然矩阵的加减乘也是十分的重要，国内外都是如此，进行大型的科研项目，涉及到复杂的线性代数，行列式，以及电路分析图都会用到矩阵的基本运算。但是就目前来看，学生对矩阵运算的研究还很少，不够理解和熟悉，于是我们就要提供更多的信息和软件的帮助。-Matrix addition and subtraction, multiplication is of course very important, are so at home and abroad, large-scale research projects, involving complex linear algebra, determinants, and circuit analysis diagram of the basic matrix operations are used. But for now, the students study for matrix operations, little, not enough to understand and become familiar with, so we have to provide more information and software to help.
