When I run my code, results will appear but my results just won't show on the graph:

K = 1

i = sqrt(-1);

n=0;

for w = 0.1:1000

n=n+1;

A(n) = w;

G(n) = K/((i*w)*((i*w)+1.71)*((i*w)+100));

end

M(n) = abs(G(n));

F(n) = 20*log(M(n));

semilogx(w,F)

You were just plotting a single point. Check the indexing of variables after the for loop.

K = 1;

i = sqrt(-1);

n=0;

W = 0.1:1000;

for w = W

n=n+1;

A(n) = w;

G(n) = K/((i*w)*((i*w)+1.71)*((i*w)+100));

end

M = abs(G);

F = 20*log(M);

semilogx(W,F)

I'm not 100% sure but I'd guess you want the last line to be:

semilogx(A,F)

because otherwise everything is plotting at the same value on the x-axis.
