我有一个matlab文件，工作正常，

我正在尝试使用自动编码器对其进行转换，但是出现错误，

??? Subscripting into an empty matrix is not supported.

ct = 0;
while i <= 1800
        [xx, cc, vv] = doSomething(x, somevalue, Param1, dt);
        %things happening ...
        if something
           flowDt(ct+1) = vv;
           ct = ct + 1;
        end
end

然后我尝试在循环之前声明它，因为我收到了一个错误： ??? Undefined function or variable 'flowDt'.'

flowDt = [];
ct = 0;
while i <= 1800
        [xx, cc, vv] = doSomething(x, somevalue, Param1, dt);
        %things happening ...
        if something
           flowDt(ct+1) = vv;
           ct = ct + 1;
        end
end

现在我不知道是什么导致了这个问题： ??? Subscripting into an empty matrix is not supported.

flow是一个 Matlab 函数。这可能是问题所在。尝试更改该变量的名称

将变量初始化为0空矩阵[]

flowDt = [];

然后

flowDt = 0; was the solution

所以flowDt = 0将初始化数组，使其not empty
