Matlab tricks---plot color

The default color of MATLAB is not ugly but sometimes not convenient. I found an easy way to plot beautiful lines [1].

You just need to generate $N$N distinguishiable colors by ‘‘C = linspecer(N)’’.
`` C’’ contains the RGB values of these colors by rows.

Then you can even use the inherit function of MATLAB [3] to set color oder and line order, which is fantastic. Here is an simple example

x = linspace(0,7);
y = ones(length(x),9);
for i = 1:9
    y(:,i) = sin(x-i/5)';
end
plot(x,y)
C = linspecer(3);  %% generate 3 colors
ax = gca;
ax.ColorOrder = C;
ax.LineStyleOrder = {'-','--',':'};
