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，

col = hex2nstr(["ff 63 47","2e 8b 57","6a 5a cd"]);

%|··by Optic_css, the nStr(·) can help you get the [1,1,1]··|
%————————————————————————————————————————————————————————————
function nStr = hex2nstr(hexstr)
    % Function that helos to get the normalized str used in MATLAB color spaces
    nStr = [];
    for io = 1:length(hexstr)
        % Splitor to get the divided types, "ff 0a 89"/"ff-0a-89" -> "ff","oa","89"
        splitor = strsplit(hexstr(io), '["-",]',"DelimiterType","RegularExpression");
        % Divide the splitor into 3 pieces
        dec_ = cell2mat(splitor(1,1));
        dec__ = cell2mat(splitor(1,2));
        dec___ = cell2mat(splitor(1,3));
        % Divided by 255: "ff", and take string addtion
        nStr = [nStr;[hex2dec(dec_)/255 hex2dec(dec__)/255 hex2dec(dec___)/255]];
    end
