Error: Unexpected MATLAB expression.
Hey everyone, how are you? I have this code that WAS working not too long ago but when I come to simulate it, it doesn't wanna work and it spits out this error message. This is for a Bode plot Midband voltage amplifier circuit. I have checked my work and everything and it was working before but I don't see what I changed in it. Anyone have any ideas? Thank you :)

You need to checked carefully what you have written in the definition of G, I have spotted some * missing, there is also a missing bracket (bold one) that I can not figure out where it starts:
G=2483.71*(2 * pi*f*10) * (2 * pi*f*100)*1018/(60.7*2 * pi*f*100)*10-9+1 ) *(6.07*2*pi*f*10*10-9+1);

Why doesn't the G= have a >> in front of it? Is it on the same line as the call to text()? Anyway, that line has for ( but 5 ) so there is a mismatch in the number pf parentheses. Fix that.

G=2483.71*(2pi*f*10)(2pi*f*100)*1018/(60.7*2pi*f*100)*10-9+1)(6.07*2pi*f*10*10-9+1);
Please check this expression which says missing parenthesis.
(60.7*2pi*f*100)*10-9+1) is the problem area with no left parenthesis.
