Matlab中，为何出现：Warning: Imaginary parts of complex X and/or Y arguments ignored 请问在MATLAB程序运行时显示如下提示Warning: I...

可以把实部和虚部分开来画，x=-1:0.01:1;
y=1.6*cos(2*pi*x)+i*0.4*sin(2*pi*x);
plot(x,real(y),'b');
hold on
plot(x,imag(y),'r');
hold off
也可以画出函数的实部-虚部图：
x=-1:0.01:1;
y=1.6*cos(2*pi*x)+i*0.4*sin(2*pi*x);
plot(y,'b')
用polar函数的话可以画出函数的极坐标图。
复数的虚数部分被忽略了，在workspace中看看你画图的向量里有没有复数，如果有复数值的话，考虑用其他的画图函数。
