x1 = 3.5*ecg(2700).'; % gen synth ECG signal // Error in this line
y1 = sgolayfilt(kron(ones(1,ceil(NumSamp/2700)+1),x1),0,21); % repeat for NumSamp length and smooth
n = 1:Time*Fs';del = round(2700*rand(1)); % pick a random offset
mhb = y1(n + del)'; %construct the ecg signal from some offset
t = 1/Fs:1/Fs:Time';subplot(3,3,1); plot(t,mhb);axis([0 2 -4 4]);grid;xlabel('Time [sec]');ylabel('Voltage [mV]');title('Maternal Heartbeat Signal');
IN THE BOLD LINE IT SHOWS THIS ERROR ,IT WOULD BE A GREAT HELP FOR ME.
PLEASE HELP
