Leetcode 566. Reshape the Matrix 矩阵变形(数组,模拟,矩阵操作) 题目描述 在MATLAB中,reshape是一个非常有用的函数,它可以将矩阵变为另一种形状且保持数据不变. 已知一个由二维数组表示的矩阵,和两个正整数r(行),c(列),将这个二维数组变换为r*c的矩阵. 如果不能由原矩阵转换为r*c的矩阵就输出原矩阵,否则输出转换后的矩阵. 测试样例 Input: nums = [[1,2], [3,4]] r = 1, c = 4 Output: [[1,2,…

python数组和矩阵使用总结 1.数组和矩阵常见用法 Python使用NumPy包完成了对N-维数组的快速便捷操作.使用这个包,需要导入numpy. SciPy包以NumPy包为基础,大大的扩展了numpy的能力.因此只要导入了scipy,不必在单独导入numpy了!为了使用的方便,scipy包在最外层名字空间中包括了所有的numpy内容. 本文还是区分numpy中实现的和scipy中实现的. 以下默认已经:import numpy as np 以及 impor scipy as sp num…
