在MATLAB中声明一个全局变量 [英] Declaring a global variable in MATLAB
问题描述
请不要回应:
全球xyz;
因为我也可以阅读帮助文件。
我声明了一个全局变量<$ c
$ p $ function [x] = test($ c $ x $)$
,然后做了这样的事情:
全球x;
test1();
end
函数 test1()
function test1()
x = 5;
end
当我运行 test()
,我的输出是 x = []
。有没有办法让它输出 x = 5
,或者是我定义 x
的任何东西,功能?在C中,这将是一个外部变量,我认为使它成为一个全局变量应该能够实现这一点。 您需要宣布 x
为全局变量在每个范围内(即功能/工作区),你希望它被共享。因此,您需要将 test1
写为:
$ b
function test1()
global x;
x = 5;
end
Is there a way to declare global variables in MATLAB?
Please don't respond with:
global x y z;
Because I can also read the help files.
I've declared a global variable, x
, and then done something like this:
function[x] = test()
global x;
test1();
end
Where the function test1()
is defined as:
function test1()
x = 5;
end
When I run test()
, my output is x = []
. Is there a way I can make it output the x=5
, or whatever I define x
to be in a separate function? In C, this would be an external variable, and I thought making it a global variable should accomplish just that.
You need to declare x
as a global variable in every scope (i.e. function/workspace) that you want it to be shared across. So, you need to write test1
as:
function test1()
global x;
x = 5;
end
