$$ \frac {\mathrm{d} life} {\mathrm{d} t} = \begin{cases} 📕\text{(study)} &\quad \text{if your boss observes you} \\ 🐟\text{(slack off)} &\quad \text{if your lover observes you} \end{cases} $$

模式

非文本文件

git repository 存放个人自己所做的, 而 pdf 等之类的就 ignore, 最后将整体(pdf 之类的)放到网盘

技巧:

  • 指定放入网盘的文件名满足*-pan的形式

mlx 文件

将这个步骤脚本化

导出 pdf

可以用markdown preview enhanced, 用 docsify 渲染后打印 pdf 太丑了

自动保存图像

matlab:

[~, filename, ~] = fileparts(matlab.desktop.editor.getActiveFilename);
saveas(gcf, sprintf('../figure/%s_%s.png', filename, imgName));

mathematica:

fileName = NotebookFileName[];
curDir = NotebookDirectory[];
SetDirectory[curDir];
fileBaseName = FileBaseName[fileName]
SetName[n_] := ToString[StringForm["../figure/``_``.png", fileBaseName, n]];

fig02 = Plot[Hfabs, {f, - (fs/2), fs/2}]
Export[SetName["1"], fig02];

突出主逻辑

艺术性, 左边是主逻辑, 右边是 observe

function X = FFT_prime(xs)
theta = reArrange(xs);                          ; theta = sym(theta)
while getCols(theta) ~= 1
                                                ; disp('---------' + string(getRows(theta)));
    [alpha, beta] = partition(theta);           ; alpha, beta
    rotateM = rotateMatrix(getRows(theta));     ; W = sym(rotateM)
    phi_1 = alpha + rotateM*beta;
    phi_2 = alpha - rotateM*beta;
    theta = [phi_1; phi_2];                     ; simplify(theta)
end
X = theta;
end

优雅

{k1, k2, k3} = Map[Subscript[k, #1]&, {1, 2, 3}]

思考

labels = [
    draw(@(x) x, 'k');
    draw(f_curry(2), 'b');
    draw(f_curry(1/4), 'r');
    draw(f_curry(0), 'c');
    draw(f_curry(-3), 'g');
    ];

有点意思, 一行一行的语句, 可以看作是列向量, 仅仅是形式上而已, 用的不过是返回值

哲学

  • too long; don't read
  • 逐步迭代, 没必要去重构之前的代码, 因为会重复写, 逐步提升就好了

局部代码块

#{
  let vecX = [$bold(mono(i))$]
  let vecY = [$bold(mono(j))$]
  let accForm(sub) = [
    $bold(a)_sub &= acc(x, sub) vecX + acc(y, sub) vecY$
  ]

  $
  cases(
    accForm(1) &&= - g/59 vecY,
    accForm(2) &&= g/59 vecY,
    accForm(3) &&= - (13 g)/59 vecY,
    accForm(4) &&= (11 g)/59 vecY
  )
  $
}

常用:

#import "@preview/physica:0.9.2": *
#import "@preview/colorful-boxes:1.2.0": *

#set math.equation(numbering: "(1)")
#show link: it => text(fill:blue, underline(it))

#show ref: it => {
  let eq = math.equation
  let el = it.element
  if el != none and el.func() == eq {
    // Override equation references.
    numbering(
      el.numbering,
      ..counter(eq).at(el.location())
    )
  } else {
    // Other references as usual.
    it
  }
}

便签

$
sigma_(x x) &= E epsilon_(x x)
#place(dx: 10pt, dy:-15pt, stickybox(width: 2.5cm, [
  #set text(size: 8pt)
  泊松比$nu = 0$
]))
$
#let acc(..sink) = {
  let args = sink.pos()
  if args.len() == 1 {
    let var = args.at(0)
    $dot.double(var)$
  } else if args.len() == 2 {
    let var = args.at(0)
    let sub = args.at(1)
    $dot.double(var)_sub$
  } else {
    none
  }
}
