create a script that will be able to analyze ecg, blood pressure and integrated msna signals and calculate the amplitude of msna, frequency and incidence of burst in matlab

main.m
% Remove DC offset from MSNA signal
msna = msna - mean(msna);

% Filter MSNA signal to remove noise
% Use a bandpass filter with passband between 0.1 Hz to 5 Hz to extract bursts
[b, a] = butter(2, [0.1 5]/(1000/2), 'bandpass');
msna_filt = filtfilt(b, a, msna);

% Calculate MSNA amplitude
amp = max(msna_filt) - min(msna_filt);

% Calculate MSNA frequency
[~, msna_peaks] = findpeaks(msna_filt);
if length(msna_peaks) > 1
    freq = 1000/mean(diff(msna_peaks));
else
    freq = 0;
end

% Calculate MSNA incidence of bursts
burst_threshold = 2*std(msna_filt); % set threshold as 2 standard deviations above mean
burst_idx = find(msna_filt > burst_threshold);
incidence = length(burst_idx)/length(msna_filt);

% Plot original and filtered MSNA signals
subplot(2,1,1);
plot(msna);
title('Original MSNA signal');
subplot(2,1,2);
plot(msna_filt);
title('Filtered MSNA signal');
