’0’)中的0改成o./zhidao/pic/item/242dd42a2834349bfd8e0ffecbea15ce37d3bec5把plot(a,b.baidu。我在matlab2013b下正确执行没有任何错误.hiphotos:///zhidao/wh%3D600%2C800/sign=/zhidao/wh%3D450%2C600/sign=d340b4b59b25bc312b08099c6befa187/242dd42a2834349bfd8e0ffecbea15ce37d3bec5://g://g.jpg" target="_blank" title="点击查看大图" class="ikqb_img_alink"><img class="ikqb_img" src="http.hiphotos.jpg" esrc="http：<a href="http
前面都一样endplot(a,b,’o’)hold ont=0:1;plot(t,t)??? plot(a,b,’o’)
|Error: Missing variable or function.亲！你好！还是不行？请问咋回事？
你是把整段代码放在一个m文件里运行的吗？
是啊！在一个command window里面运行的！
不是……是要新建一个m文件，把这些内容复制进去，然后运行。
& 亲！你好！还是不行！我是个新手！整个程序那部分在m文件中，那部分在command window中！你看看我的问题在哪？最好能截屏看看！
这叫在m文件中 明白么？

第一个问题 最后缺少一个end 添加之后就OK第二个问题 R 在使用之前没有定义，请先定义具体值，然后再使用！

FUNCTION Add new function. New functions may be added to MATLAB&#39;s vocabulary if they are expressed in terms of other existing functions. The commands and functions that comprise the new function must be put in a file whose name defines the name of the new function, with a filename extension of &#39;.m&#39;. At the top of the file must be a line that contains the syntax definition for the new function. For example, the existence of a file on disk called STAT.M with: function [mean,stdev] = stat(x) %STAT Interesting statistics. n = length(x); mean = sum(x) / stdev = sqrt(sum((x - mean).^2)/n); defines a new function called STAT that calculates the mean and standard deviation of a vector. The variables within the body of the function are all local variables. See SCRIPT for procedures that work globally on the work- space. A subfunction that is visible to the other functions in the same file is created by defining a new function with the FUNCTION keyword after the body of the preceding function or subfunction. For example, avg is a subfunction within the file STAT.M: function [mean,stdev] = stat(x) %STAT Interesting statistics. n = length(x); mean = avg(x,n); stdev = sqrt(sum((x-avg(x,n)).^2)/n); %------------------------- function mean = avg(x,n) %MEAN subfunction mean = sum(x)/n; Subfunctions are not visible outside the file where they are defined. Normally functions return when the end of the function is reached. A RETURN statement can be used to force an early return.
