Hi
I'm kinda new to Matlab
Wot i'm trying to do is draw a Bode plot without using the inbuilt 'bode' function.
i tried using logspace command for the purpose but all in vain
can anyone help???
Here is the code i had written
a=[0 0 25];
b=[1 4 25];
w=logspace(-1,2)
hold on
w1=0.1:100;
for i=1:100
x=polyval(a,j*w1(i));
y=polyval(b,j*w1(i));
z=x/y;
b=abs(z);
plot(20*log10(B),w(i),'+')
hold on
end
pls help
thx a lot
