矩阵化编程: 矩阵的逻辑标示法索引方式,和前面提到的算符和表达式的“数组运算”方式结合可以产生强大的“矩阵化”编程方式,用这种方式替代循环结构不仅可以简化代码,还可以大大提高代码执行效率,例子如下。 程序要计算下面的函数: 其中theta在二维下为10/(7*pi*h^2),函数图像如下所示(类高斯函数): 下面比较普通循...
The ‘r–’ string is a line specification. Each specification can include characters for the line color, style, and marker. A marker is a symbol that appears at each plotted data point, such as a +, o, or. For example, ‘g:’ requests a dotted green line with * markers. “r–”...

“Matlab”是“MatrixLaboratory” 的缩写,中文“矩阵实验室”,是强大的数学工具。本文侧重于Matlab的编程语言侧面,讲述Matlab的基本语法,以及用Matlab语言进行程序设计。值得一提的是,Matlab从R2014a版本开始支持中文语言了! 1.基本概念 Matlab默认启动后界面: ...
基于python-opencv程序对光流法的理解 光流法的定义 Lucas-Kanade光流原理 Shi-Tomasi角点检测 python-opencv代码demo 光流法的定义 光流法是空间运动物体在观察成像平面上的像素运动的瞬时速度,是利用图像序列中像素在时间域上的变化以及相邻帧之间的相关性来找到上一帧跟当前帧之间存在的对应关系,从而计算出相邻帧之间...
