How to convert point plot to line plot?

Hi,

I would like to ask if it is possible to convert a plot which has coordinate points to a line plot that link such coordinates.

If so, how do I convert? Thanks in advance.

My code is below:

Fp = 1000; %Bandpass Freq

Fs = 2000; %BandStop Freq

SF = 10000; %Sampling Freq

Pr = 0.1; %Passband ripple

Sr = 0.001; %Stopband ripple

N = 13;

L = 14;

M = 7;

sll = -10;

u = cosh((1/N)*acosh(10^(-sll/20)));

mainbc = 0.05*pi; %center of desired mainband

bw = 0.1; %bandwith

ti = 1; %variance

for ang=0:0.001*pi:0.2*pi

xa =-(0.5*pi*sin(bw*(ang - mainbc)))^M;

xb = 2*ti^2;

e = exp((xa/xb));

H = cos((L - 1)*acos(u*e))

plot(ang,H,'b.'),grid on;hold on

end

Fp = 1000;  %Bandpass Freq
Fs = 2000;  %BandStop Freq
SF = 10000; %Sampling Freq
Pr = 0.1;  %Passband ripple
Sr = 0.001;  %Stopband ripple
N = 13;
L = 14;
M = 7;
sll = -10;
u = cosh((1/N)*acosh(10^(-sll/20)));
mainbc = 0.05*pi; %center of desired mainband
bw = 0.1;         %bandwith 
ti = 1;           %variance

% compute the result as a vector
ang=(0:0.001*pi:0.2*pi);
xa =-(0.5*pi*sin(bw*(ang - mainbc))).^M;
xb = 2*ti^2;
e = exp((xa/xb)); 
H = cos((L - 1)*acos(u*e));
plot(ang,H,'b-'),grid on;hold on
