Matlab曲線的顏色、線型等引數設定方法

在Matlab繪圖時，如果繪製的曲線特別多的時候，通常需要用不同的顏色和線型區分開這些曲線，否則在黑色列印輸出影象時，使用者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這個資料結構就可以了。

41 x = 0.1:.1:10;
42 len = length(PlotStyle);
43 for i = 1:len
44     y = x.*log(x)+i*2;
45     hold on;
46     plot(x,y,'Color',PlotStyle{1,i}.Color,'LineStyle',PlotStyle{1,i}.LineStyle,'lineWidth', 2);% 這裡是呼叫上述模板結構的方法，注意引用方式，需要做到屬性和數值一一對應即可，類似鍵值對的方式
