一些奇怪的绘图方法：

matlab自定义曲线拟合

  • 定义想要拟合的曲线函数：

以function的形式定义，参数以beta->list传入，例如：

1
2
3
4
5
6
function Phi = myfun1(beta,P)
    M = 10^((-8-30)/10)*0.35;
    a = beta(1);
    b = beta(2);
    Phi = M./((exp(a*b)/(1+exp(a*b))).*(1+exp(-a.*(P-b))))-M/exp(a*b);
end
  • 喂数据进行拟合，得到参数值：

在喂入数据的时候，需要给初始值。就目前我实验的结果而言，初始值极大程度影响最终拟合结果。

1
beta = nlinfit(x, y, @myfun1,[20000,0.0001])

返回的beta就是最后拟合的参数值。

结构体

定义

以y=struct(key1,value1,key2,value2...)的形式定义：

1
2
3
4
5
title_mapping=struct('AA_IS', 'AA-IS',...
    'AA_SA', 'AA-SA', ...
    'AA_minVar', 'AA-SS_{minVar}',...
    'AA_maxE','AA-SS_{maxE}',...
    'APS_EMW', 'APS-EMW');

遍历

1
2
3
4
5
6
fileds = fieldnames(title_mapping);
for i=1:length(fileds)
    k = fileds(i);
    key = k{1};
    value = title_mapping.(key);
end

字符串

字符串用 " " 字符用 ’ ’

name_space = ["Method1", "Method2"];

maltab 图的大小

有时候需要控制图的大小，比如控制为2:1的矩形图，为了在论文里面大小一致，建议用代码实现

1

figure('Position', [500, 300, 560, 420]); % 一般matlab默认图的大小为 560*420 
figure('Position', [500, 300, 560, 560/2]); %

  • 绘制完图像后，命令行输入magnify
  • 然后CTRL+鼠标左键选择放大位置
  • 保持左键，松开CTRL，（按住alt）通过- +键缩小放大图像
  • 在插入中插入箭头

20231206：

Magnify后EPS图可能会变糊（不知道在其他地方是否也是如此），原因是因为 如果图比较复杂，渲染器会变成OpenGL，要在导出设置里面修改为paintes就可以了。

matlab自带load读取数据是结构体，不够方便。使用自定义函数，第一个参数为文件路径，第二个参数为保存时的变量名，返回数据。

function out = myload(path, name)
    data = load(path);
    out = eval(['data.', name]);
