MarkDown사용법

MarkDown Table

  • posting 날짜는 파일 이름이 아니고, MARKDOWN 파일 속의 날짜.

You’ll find this post in your _posts directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run jekyll serve, which launches a web server and auto-regenerates your site when a file is updated.

Jekyll requires blog post files to be named according to the following format:

YEAR-MONTH-DAY-title.MARKUP

Where YEAR is a four-digit number, MONTH and DAY are both two-digit numbers, and MARKUP is the file extension representing the format used in the file. After that, include the necessary front matter. Take a look at the source for this post to get an idea about how it works.

Jekyll also offers powerful support for code snippets:

def print_hi(name)
  puts "Hi, #{name}"
end
print_hi('Tom')
#=> prints 'Hi, Tom' to STDOUT.
\[D_{KL}(p \| q) = \int_x p(x) \log \frac{p(x)}{q(x)} dx\]

이 식의 의미

\[\begin{eqnarray} \widehat{g}_t^{acer} &=& \bar{\rho}_{t} \nabla_{\theta} \log \pi_{\theta}(a_t| x_t) [Q^{ret}(x_t, a_t) - V_{\theta_v}(x_t)] \\ & & + \underset{a \sim \pi}{\mathbb{E}} \left( \left[\frac{\rho_{t}(a) - c}{\rho_{t}(a)} \right]_+ \hspace{-3mm} \nabla_{\theta} \log \pi_{\theta}(a| x_t)[Q_{\theta_v}(x_t, a)- V_{\theta_v}(x_t)] \right) \end{eqnarray}\]

행렬 \(\begin{pmatrix} 1 & a_1 & a_1^2 & \cdots & a_1^n \\ 1 & a_2 & a_2^2 & \cdots & a_2^n \\ \vdots & \vdots& \vdots & \ddots & \vdots \\ 1 & a_m & a_m^2 & \cdots & a_m^n \end{pmatrix}\)

\[\begin{eqnarray} f(x) &=& \int_0^\infty g(t,x) dt \\ &=& z(x) \end{eqnarray}\] \[\begin{eqnarray} y &=& x^4 + 4 \nonumber \\ &=& (x^2+2)^2 -4x^2 \label{eq0001}\\ &\le&(x^2+2)^2 \label{eq0002} \end{eqnarray}\]

\(\eqref{eq0001)\)과 식\((\eqref{eq0002})\) \(\eqref{eq0001)\)과 식\((\eqref{eq0002})\)

수식에 reference 달기 성공: \(\begin{align} g &= \int_a^b f(x)dx \label{eq1}\tag{1} \\ a &= b + c \label{eq2}\tag{2} \end{align}\) See \((\ref{eq1})\) and \((\ref{eq2})\)

\(\color{red}{ \begin{align} g &= \int_a^b f(x)dx \label{eq3}\tag{3}\\ a &= b + c \label{eq4} \tag{4} \end{align}}\) See \((\ref{eq3})\) and \((\ref{eq4})\)
