mdshare#

Type markdown on the left, see it rendered on the right. The document is compressed and stored in the URL itself, so sharing the page is just copying the link: there is no server and nothing is uploaded.

Math#

Inline math like $e^{i\pi} + 1 = 0$ works, and so do display equations:

\int_{-\infty}^{\infty} e^{-x^2}\,dx = \sqrt{\pi}

\begin{pmatrix} a & b \\ c & d \end{pmatrix} \begin{pmatrix} x \\ y \end{pmatrix} = \begin{pmatrix} ax + by \\ cx + dy \end{pmatrix}

Code#

import numpy as np

def gaussian(x, sigma=1.0):
    """The integrand from the equation above."""
    return np.exp(-x**2 / sigma**2)

x = np.linspace(-4, 4, 1000)
print(np.trapezoid(gaussian(x), x))  # ~ sqrt(pi)
