firstderivative

MATLAB M文件例子 最简单的精通MATLAB工具箱的函数之一提出了一个共同的问题。MATLAB函数gcf返回当前图形的句柄。但是，它有一个副作用。如果图形不存在，gcf就创建一个，并返回它的句柄。如果想寻找一个图形是否存在于头一个位置，要是没有，又不得不创建，怎么办？函数mmgcf正好实现由其内容所描述的工作。(MATLAB M file example of the simplest function of proficiency in one of MATLAB toolbox put forward a common problem. MATLAB function to return to the current GCF handle graphics. However, it has a side effect. If the graph does not exist, gcf on to create one and return its handle. If you want to find a graphic exist in the first position, if not, they have created, how should I do? Function mmgcf realize its content is described.)
