Matlab曲線的顏色、線型等參數設置方法
在Matlab繪圖時，如果在同一視窗內繪制的曲線特別多的時候，通常需要用不同的顏色和線型將其區分開，否則在黑白色打印輸出圖像時，用戶無法辨別不同屬性的曲線。下面是的曲線顏色的配置模板，大家可以直接修改使用，直接引用PlotStyle這個數據結構就可以了。

%% PlotStyle是一個元胞，其中每個元素是一個結構體，每個結構體內含有兩個字段，即顏色字段Color和線型字段LineStyle 5 PlotStyle={ 6 struct('Color',[1,0,0],'LineStyle','-'),... 7 struct('Color',[0,1,0],'LineStyle','-'),... 8 struct('Color',[0,0,1],'LineStyle','-'),... 9 struct('Color',[0,0,0],'LineStyle','-'),...% 10 struct('Color',[1,1,0],'LineStyle','-'),...%yellow 11 struct('Color',[1,0,1],'LineStyle','-'),...%pink 12 struct('Color',[0,1,1],'LineStyle','-'),... 13 struct('Color',[0.5,0.5,0.5],'LineStyle','-'),...%gray 14 struct('Color',[136,0,21]/255,'LineStyle','-'),...%dark red 15 struct('Color',[255,127,39]/255,'LineStyle','-'),...%orange 16 struct('Color',[0,162,232]/255,'LineStyle','-'),...%Turquoise 17 struct('Color',[163,73,164]/255,'LineStyle','-'),...%purple 18 struct('Color',[1,0,0],'LineStyle','--'),... 19 struct('Color',[0,1,0],'LineStyle','--'),... 20 struct('Color',[0,0,1],'LineStyle','--'),... 21 struct('Color',[0,0,0],'LineStyle','--'),...%
