How to time shift a signal

Hi,

I have this code,

clear all; close all; clc;
fc=30e3;
for n=1:3;
tc = gauspuls('cutoff',fc,0.4,[],-40);
t = -tc : 1e-7 : tc; 
yi = gauspuls(t,fc,0.6); 
plot(t,yi)
hold on
fc=fc+10e3;
end

It is supposed to generate 3 gaussian pulses each at 30kHz, 40kHz and 50kHz respectively. However they overlap each other and I want them to be time shifted in such a way that first is 30k then 40k and then 50k.

Thanks

You can just create a vector of zeros and fill it with the pulses

    fc=30e3;
    t = -tc : 1e-7 : tc; 
    y = zeros(3*length(t),1);
    startidx = 1;
    endidx = length(t);
    for n = 1:3
      yi = gauspuls(t,fc,0.6); 
      y(startidx:endidx) = yi;
      fc = fc+1e4;
      startidx = startidx+length(t)+1;
      endidx = endidx+length(t)+1;
   end
   plot(y)

hi, try :

 clear all; close all; clc;
fc=30e3;
for n=1:3
tc = gauspuls('cutoff',fc,0.4,[],-40);
t = -tc : 1e-7 : tc; 
yi = gauspuls(t+n*1e-5,fc,0.6); 
plot(t,yi)
hold on
fc=fc+10e3;
end
