matlab初阶绘图 plot(cos(0:pi/20:2*pi)) matlab将会清除之前的图像保留最新的图 plot(cos(0:pi/20:2*pi)); plot(sin(0:pi/20:2*pi)); what can we do to solve this problem? hold on plot(cos(0:pi/20:2*pi)); plot(sin(0:pi/20:2*pi)); hold off 曲线性质 plot(x,y,“str”) hold on plot(cos

MATLAB进阶画图 Logarithm Plots x = logspace(-1,1,100); % 10的-1~1生成100个等差数列次方， y = x.^2; subplot(2,2,1); plot(x,y); % 二次函数 title('Plot'); subplot(2,2,2); semilogx(x,y); % plot(log10(x),y) title('Semilogx'); subplot(2,2,3); semilogy(x,y); % plot
