%一个MATLAB字符串是一个char型数组。每一个字符占2个字节。当字符串被赋值于 %一个变量时,这个变量将被自动创建为字符变量. %一个专门的函数ischar常用来判断一个变量是否为字符数组 ifischar(str1) disp('str1isstringarrayvariable'); end str1isstringarrayvariable ...
In MATLAB, strings of characters are stored in string arrays when you use double quotes (") or in character arrays if you use single quotes ('). If you use both single and double quotes in an array assignment, the array will be promoted to a string array....

的转换,通常的方法有如下: ToString(): 转换数据类型为字符串(string)。此与C#语法相同。 IsBool()和AsBool()是把字符串转换为布尔值(Boolean...()是把字符串转换为双精度(decimal)。 IsDateTime()和AsDateTime()是把字符串转换为时间类型(DateTime) 下面有举列一个动画演示: 转载于:https ...
实际上mexFunction是没有这么简单的,我们要对用户的输入自变量的个数和类型进行测试,以确保输入正确。如在add函数的例子中,用户输入char array便是一种错误了。 从上面的讲述中我们总结出,MEX文件实现了一种接口,把C语言中的计算结果适当地返回给Matlab罢了。当我们已经有用C编写的大型程序时,大可不必在 Matlab里重...
