MATLAB plot Tiny Tricks -- by Optic_css

Use set(gca, ·, ·, ·, ···) HANDLE for editing

[纪录] 这里是我常常应用的MATLAB制图Code，记录下来是为了当前更快地实现一些根本的制图Setting类的操作，换句话说，当作查阅的备用叭... ...

上面所展现的Codes是一些根本的绘图Setting，很容易能看懂，根本蕴含了对于一张图像

  • 'colormap'
  • 'grid'
  • 'box'
  • 'xtick'、'ytick'、'LinwWidth'、'FontName'、'Color'
  • 'xlabel'、'ylabel'、'title'、'legend'
  • 'axis'

的设置，这样曾经算是根本满足了需要... ...

上面则是一个小trick，对于如何将图窗background变通明的Setting办法，次要是前面对于'InvertHardCopy'的setting，这是属于某个凶恶分享者的资源，

A useful (MAYBE) HEX-RGB to String convertor

上面是一个将hexadecimal RGB色调代号转换为MATLAB实用的色调值，也即

  • 输出一个$\rm string:\ ''ff 63 47''/''ff-63-47''$
  • 输入一组向量

    $\rm col=1\times3$
    $1.000000000000000\ \ \ 0.388235294117647\ \ \ 0.278431372549020$

设计中采纳inline function $\rm hexstr(·)$，做成了一个vector函数的格局，当需要很大的时候，可能显著减小calling所带来的耗费，
