undefined reference toc语言

"undefined reference" 是一个编程错误，通常指在编译时找不到某个函数或变量的定义。这可能是因为代码中缺少某个库或头文件，或者是因为代码中存在语法错误。需要检查代码并解决问题。 "toc语言" 是什么意思不是很清楚，需要更多的上下文来理解。

matlab toc

在MATLAB中，toc函数用于计算从调用tic函数到当前时刻的时间差，从而得到代码的执行时间。需要注意的是，tic和toc函数必须在同一个MATLAB命令窗口中使用，否则toc函数无法正确计算时间差。为了确保结果的准确性，应该多次运行代码并取平均值。下面是一个示例代码：

tic;
% 这里是你的代码
toc;

在这个示例中，tic函数用于记录当前时刻的时间，然后执行你的代码，最后使用toc函数获取从调用tic函数到当前时刻的时间差，并输出代码的执行时间。请注意，这只是一个简单的示例，你需要将你的实际代码替换到注释部分。

gitlab toc

GitLab does not provide a built-in feature to generate a table of contents (TOC) for Markdown files directly within the platform. However, you can manually create a TOC using Markdown syntax. Here's an example:

## Table of Contents

- [Section 1](#section-1)
- [Section 2](#section-2)
  - [Subsection 1](#subsection-1)
  - [Subsection 2](#subsection-2)
- [Section 3](#section-3)

## Section 1

Content of section 1...

## Section 2

Content of section 2...

### Subsection 1

Content of subsection 1...

### Subsection 2

Content of subsection 2...

## Section 3

Content of section 3...

In this example, the TOC is manually created by linking to the corresponding headings using anchor links (`#` followed by the lowercase heading text, replacing spaces with hyphens). You can place this TOC at the beginning of your Markdown file to provide navigation.

Keep in mind that this approach requires you to maintain the TOC manually if you make changes to the headings in your document.
