x=linspace(0.0001,0.01,1000); y=sin(1./x); plot(x,y) axis([0.005 0.01 –1 1]) 为什么无法绘图

x=linspace(0,2*pi)在matlab中是什么意思 MATLAB中,x=linspace(0,2*pi, x=linspace(0.0001,0.01,1000); y=sin(1./x); plot(x,y) axis([0.005 0.01 –1 1]) 为什么无法绘图 rho=linspace(0,1,100); theta=linspace(0,2*pi,100); x=rho'*cos(theta); y=rho'*sin(theta) 为什么要加转置符号?
