什么是％＃ok< SAGROW>评论是什么意思？ [英] What does %#ok<SAGROW> comment mean in MATLAB?

问题描述

我遇到过许多具有％＃ok< SAGROW> 注释的MATLAB代码。

I've encountered many MATLAB codes which have a %#ok<SAGROW> comments. This comment is used in different circumstances and I can't figure it out what it means.

例如：

i = 1; 
flag = true;
for l = 1:k
    while(flag==true)
        if(probs(i)~=0)
            leaves(l).val = i-1; %#ok<*SAGROW>
            leaves(l).zero = '';
            leaves(l).one = '';
            leaves(l).prob = probs(i);
            i = i + 1; 
            flag = false;
        else
            i = i+1;
            flag = true;
        end
    end
flag =true;
end

还有其他引用这个注释，对于instace：

推荐答案

它抑制 mlint 警告。在这种特定情况下，它不是预先分配数组。

It suppresses mlint warnings. In this specific case, it is about not pre-allocating an array.

mlint 是Matlab的静态代码分析工具之一。它会发现可能的错误并显示警告。

mlint is one of the static code analysis tools that Matlab has. It finds possible errors and shows warnings.

编辑（1）：
我刚刚注意到您的问题是关于 SAGROW ，而不是 AGROW 。我找不到它。我的猜测是，它是一个旧的/新的mlint语法。

Edit(1): I've just noticed that your question is about SAGROW, not AGROW. I could not find it. My guess is that it is an old/new mlint syntax.
