为什么我的代码运行之后只出现一个图,

是xlabel不是xlable

在matlab绘图中,x=0:0.1:4*pi;此语句中,0,0.1, 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 funct matlab 如何做分段函数的绘图 y=sin(x)*(-2*pi=0) matlab二维绘图,函数：x=b+0.1*cos(a) y=[1-0.1*b*cos(a)]*cos(a) 其中a是0到2*pi的角度,b是在区间【0,10】连续取值.目的是想画出这曲线,但我用matlab画总出现加法错误.还请大神解答疑惑并给予正确命令·· Matlab中“x=0:pi/100:2*pi”步长为什么设定是pi/100啊.绘图曲线是 y=2e^(-0.5x)sin(2pix) matlab绘图中的语法t=0:0.1:2*pi;y=sin(t);plot(t,如题~ matlab fplot函数创建 y=funfplot(x) y=sin(1/tan(pi*x)) 在[-0.1,0.1]上 令误差tol=2e-4 绘图 matlab参数方程绘图问题t=0:pi/1000:3*pi k=fix(2*t/pi)+1; y=0.5*sqrt(2)*sin(0.5*k*pi+0.25*pi)+k*sin(t); x=0.5*sqrt(2)*cos(0.5*k*pi+0.25*pi)+k*cos(t); plot(x,y) axis equal 为什么不能运行啊, matlab 构造向量x=0:pi/10:2*pi x=[0:0.1:2*pi]在matlab中是什么意思?
