matlab 写了个简单的函数,可为什么说 The variable y does not exist.
没有定义 y 变量
不是符号计算,数值解

楼上说的有问题,The variable y does not exist意思是变量y不存在
还有,不能直接对函数文件运行,函数要放在主文件里调用才可以

在VC中运行程序时为什么说the file does not exist? The specified directory does not exist the index ’GetTodayRandom’does not exist The password you provided does not exist! user does not exist Does not exist Perfection does not exist Index does not exist 请教matlab的exist函数的用法? The name 'Session' does not exist in the current context . The name 'CheckExtension' does not exist in the current cont 英语翻译The registration ID ( rogguvidflabatvi ) does not exist
