matlab二维绘图
x=0:0.1*pi:4*pi;
y=sin(x);
z=cos(x);
v=[0,15,-2,2];axis(v)
subplot(2,2,1);plot(x,y,'--r');xlable('x-axis');ylable('y=sinx');title('sine function image');
subplot(2,2,2);plot(x,z,'-b');xlable('x-axis');ylable('z=cosx');title('cosine function image' );
subplot(2,2,3);plot(x,y+z,'-.k');xlable('x-axis');ylable('y+z=sinx+cosx');title('sine and cosine fuction image');
subplot(2,2,4),
plot(x,y,'--r')
hold on
plot(x,z,'-b')
plot(x,y+z,'-.k')
legend('y=sinx','z=cosx','y+z=sinx+cosx')
hold off
为什么我的代码运行之后只出现一个图,

x=0:0.1*pi:4*pi;
y=sin(x);
z=cos(x);
v=[0,15,-2,2];axis(v)
subplot(2,2,1);plot(x,y,'--r');
xlabel('x-axis');ylabel('y=sinx');title('sine function image');
subplot(2,2,2);plot(x,z,'-b');xlabel('x-axis');ylabel('z=cosx');title('cosine function image' );
subplot(2,2,3);plot(x,y+z,'-.k');xlabel('x-axis');ylabel('y+z=sinx+cosx');title('sine and cosine fuction image');
subplot(2,2,4),
plot(x,y,'--r')
hold on
plot(x,z,'-b')
plot(x,y+z,'-.k')
legend('y=sinx','z=cosx','y+z=sinx+cosx')
hold off

是xlabel不是xlable

matlab二维绘图x=0:0.1*pi:4*pi;y=sin(x);z=cos(x);v=[0,15,-2,2];ax matlab中 x=[0:0.15:2*pi]; y=[0:0.15:2*pi]; z=sin(y‘)*cos(x); matlab 如何做分段函数的绘图 y=sin(x)*(-2*pi=0) 用MATLAB画图,例>> x=0:pi/15:2*pi; >> y1=sin(x)； >> y2=cos(x)； >> matlab >> syms x y;x=linspace(0,2*pi,60);y=(sin(x)*cos(5*x)) 如何用matlab画y=267*sin(x)*sin(x)*cos(x);在（0 2pi）区间 matlab基础 x=0:0.1:2*pi;y1=sin(x);y2=cos(x);z=[y1,y2];plot(x,z matlab中y=(0.5+3.*sin(x*pi/180)./(1+x^2)).*cos(x*pi/180);哪里错了 matlab中如何画图!x=-pi:0.1:pi; y=cos(x)/cos(2*x);plot(x.y) Matlab u(x,t)=sin(5*pi*x)cos(5*pi*t)+2sin(7*pi*x)cos(7*pi*t) Matlab的作图命令,x = 0:pi/100:2*pi; y = sin(x); plot(x,y) 已知x≥y≥z≥pi/12,x+y+z=pi/2,问cos x *sin y*cos z 的最大值和最小值
