1. 创建MATLAB函数文件 我们可以直接创建一个后缀为.m的MATLAB脚本(Script)文件或者通过MATLAB新建一个函数(Function)文件,如下图,两个方式建立的文件格式是一样的,只不过用第二种方法创建的文件会自动生成一个模板(template),更加方便也更为推荐,我以这个方法为代表进行接下来的说明。 用新建一个函数的方式生成的M...
本节将介绍一些Matlab R2011a中与图像处理密切相关的数据结构及基本操作,如基本文件操作、变量使用、程序流程控制、打开和关闭图像以及图像格式转换和存储方式等。这些都是后续将要学习的图像处理算法的基础。2.1.1 Matlab软件环境1.软件界面图2.1所示是运行于32-bit Windows操作系统上的Matlab R2011a界面。软件主界面...
This returns function handleyrepresenting a function of one variable defined by the expression on the right. The variables in parentheses following the @ symbol (in this case, onlyx) specify variables of whichyis a function. The functionycan now be evaluated by calling it like an...

1function PlotTest(n)2%编写一个简单的函数,对plot进行简单封装一下3plot(1:n,1:n);4%测试正确,才可以进行下一步工作 注意,混编必须是m函数function的形式才能被调用。上述函数简单测试一下,没有问题(复杂的函数一定要多测试,否则后续调试非常困难)。继续下一步。
