我们上一篇已经详细的分析了利用雅克比矩阵可以由给出的关节速度求解末端执行器的速度,除此之外,雅克比矩阵还可以体现末端执行器上施加的力和关节上施加的力矩之间的关系。今天主要介绍的就是这种关系。 在这之前,先说两点后面要用到的知识: (1)虚功原理:对于一个物体,只需要考虑主动力,不用 ...
In MATLAB, there is a very useful function called 'reshape', which can reshape a matrix into a new one with different size but keep its original ...
Given a matrix consists of 0 and 1, find the distance of the nearest 0 for each cell. The distance between two adjacent cells is 1. Example ...
给定一个矩阵,把零值所在的行和列都置为零。例如: 1 2 3 1 0 3 1 1 1 操作之后变为 1 0 3 0 0 0 1 0 1 方法1: 赋值另存一个m*n的矩阵,在原矩阵为零的值相应置新的矩阵行和列为零。额外空间为O(m*n). 方法2: 两个 ...
Given a m x n matrix, if an element is 0, set its entire row and column to 0. Do it in place. click to show follow up. Follow up: Did you ...
