ezplot(sin(x)^2,[-4,4])

ezplot('x*tan(a)-(g*(x^2))/(2*(v*v)*(cos(a)*cos(a))',[0,1200])

x=[0:pi/12:2pi]; r=-cos(2x).*sec(x); polar(x,r) [m,n]=pol2cart(r,x) plot(m,n)

在这里插入代码片

clear; A=magic(5); bar3(A);

Kaizhi=[2200,1500,600,200,300,700]; [n,m]=max(Kaizhi); TU=zeros(size(Kaizhi)); TU(m)=1; pie(Kaizhi,TU); legend('住房还贷','饮食费用','文教费','医药费用','交通费','储蓄')

zeta=-pi/12:pi/24:pi/12; r=0.5+cos(zeta); r=[0.5,r,0.5]; [x,y,z]=cylinder(r,12); surf(x,y,z),grid on
