NumPy系统是Python的一种开源的数值计算扩展。这种工具可用来存储和处理大型矩阵,比Python自身的嵌套列表(nested list structure)结构要高效的多(该结构也可以用来表示矩阵(matrix))。据说NumPy将Python相当于变成一种免费的更强大的MatLab系统。 以上引自百度百科 numpy官网:http://www.numpy.org/ 1.如何表示矩阵 矩阵...

This chapter gives facts and theorems from linear algebra and graph theory that we use in the following chapters. We include a brief introduction to Python programming with further references for more extensive study. Python codes are provided to help you learn the basics and to give you a ...
The inverse of a square and invertible matrixAin linear algebra is the matrixA-1, which when multiplied with the original matrix is equal to the identity matrixI. This can be written down as the following mathematical equation: A A-1 = I ...
