octave - 如何绘制 n=((pi-2phi)(1+2y^2)+sin(2phi)-8ycos(phi)) / ((pi-2phi)+sin(2phi)-4ycos(phi))

Question

>> y=-16:0.5:16; 
>> phi=linspace(0,4*pi,65);
>> a=((pi-2*phi)*(1+2*y.^2)+sin(2*phi)-(8*y*cos(phi)));
error: operator *: nonconformant arguments (op1 is 1x65, op2 is 1x65) #This is the error
>>b= ((pi-2*phi)+sin(2*phi)-4*y*cos(phi));

c=a/b;

错误总是我该如何解决？我想绘制函数 c。
