在Matlab中`...`有什么作用? [英] what does `...` do in matlab?

问题描述

我是Matlab的新手，但我认为...用于表示数组.但是，遵循以下几行代码证明我不知道该怎么做.有人可以给我一个线索吗?

I am new to Matlab but I thought ... is used for expressing array. Following lines of code, however, proved that I had no idea what that does. Could anybody give me a clue?

 str = sprintf('%s: sometext %d of %d, sometext %d [%d-other text %d]',...
            GROUP(ID).Name,...
            GROUP(ID).TurnNumber+1,...
            GROUP(ID).MaxTurns,...
            GROUP(ID).SetNumber,...

推荐答案

这是行继续字符串；基本上，这意味着将要遇到的行尾字符视为不存在.

It's the line continuation string; basically, it means treat the end of line character you're about to encounter as if it didn't exist.

由于换行无效:

str = sprintf('%s foo',
           'foo');

有效，因为您告诉Matlab继续阅读:

Valid because you tell Matlab to keep reading:

str = sprintf('%s foo', ...
           'foo');
