Declare a global variable in yourMATLAB Functionblock, or in the code that theMATLAB Functionblock calls. In theMATLAB Functionblock, add a variable in theSymbolspane with the same name as the global variable.
Hello! I´ve created a global variable in a main GUI. A buttom on this opens a second GUI where I need to use the global variable. Must I declare: globalMyVariable; in every function where I will use MyVariable inside the second GUI? Or there is a way to declare it once?
Also , global variables carry notable risks . Any function can access and update a global variable . Other functions that use the variable might return unexpected results . 此外,全局变量具有显著的风险。任何函数都可以访问和更新全局变量。使用该变量的其他函数可能会返回意外结果。 If you unintentionally ...
For example, I have following use case. There are bunch of helper functions in func.m file, which will use some global variable const. How can I declare them once, such that all helper functions in this function file can use them?

您可以使用global关键字将变量声明为全局变量,从而使其在整个程序中可见。另一种方法是将变量作为参数传递给需要使用它的函数。 以下是一个示例代码,演示了如何解决"Undefined function or variable"错误: 代码语言:javascript 代码运行次数:0
以下示例说明了“参数”字段的用法,用于为 2 级 MATLAB S-Function输入用户定义的参数。 此示例中的模型msfcndemo_limintm包含示例 S-Function msfcn_limintm.m: function msfcn_limintm(block) % Level-2 MATLAB file S-Function for limited integrator demo. ...
I don't think that changes anything I said though. The whole purpose of functions is that they take input arguments and can send back output arguments. You can pass out the same thing you pass in and then pass it in again next time you call ...
