Who can plot my equation? F=F(w), w0,R,L are parameters.

Best Answer

%%SECTION START
syms a(w) b(w) w w0 R L F M(w) N(w) a1(w) clear;
R = 100;               %ohms lets say
w0 = 200*pi ;       %radians per second, say
L  = 1;                  % Henry, say
clc;
the abv can be replaced by parameters of the function, later.
clc;
M(w) = w0^2 - w^2;
N(w) = R*w/L;
a(w) = M(w)*w0^2/(M(w)^2 + N(w)^2);
a1(w) = a(w)/w0^2;
b(w) = N(w)/(M(w)^2 + N(w)^2);
F(w) = (a(w)^2 +  b(w)^2)^(1/2);
%%now plot
clf;
ezplot3(F(w),a1(w),b(w));
pause(3);
hold on;
ezplot(F(w));
