Hi Everyone,

I am trying to plot a rician impulse and frequency response in App designer and the simulated object image is not staying on the screen. Can someone assist please, this is the code below:

x= (app.ExcessDelayField.Value);
y =(app.RelativePowerdBmEditField.Value);
xconverted=str2double(strsplit(x,','));
yconverted=str2double(strsplit(y,','));
if (not((length(xconverted)==length(yconverted))))
fig = uifigure;
uialert(fig,'Error! Both parameters must have the same amount of values!','Re-enter parameters!'); 
else
    
%  stem(app.Plot1,xconverted,yconverted);
% app.Plot1.YDir = 'reverse';
% xlabel(app.Plot1,'Excess tap delay');
% ylabel (app.Plot1,'Relative power (dB)');
% title(app.Plot1,'Power Delay Profile');
Carrierfrequency_Hz =app.CarrierFrequencyMHzEditField.Value*1e6;
Mobilespeed_ms=(app.MobilespeedkmhrEditField.Value*1000)/3600;
fD= (Carrierfrequency_Hz )*(Mobilespeed_ms)/(3e8); %dopplershift= Mobile_speed * Carrier frequency /speed of light
 samplerate=app.SamplerateMHzEditField.Value*1e6;
 pathdelays=xconverted*1e-9;
% release(rayChan);
ricianChan = comm.RicianChannel('SampleRate',samplerate, ...
    'PathDelays',pathdelays, ...
    'AveragePathGains',yconverted, ...
    'KFactor',10, ...
    'MaximumDopplerShift',fD, ...
    'Visualization','Impulse response');
x1 = randi([0 1],1000,1);
y1=ricianChan(x1);
