Using MATLAB, help me finding the following:

1- SignalSeg = tsig(loc(1) : loc(2));

2- Find signal segment for each loop.

3- Run findpeaks( ) on signal segment.

4- Store first peak of each segment in an array.

design an automatic detection algorithm for intracranial pressure (ICP) signals that locates the first peak following each heart beat. This is called the percussion peak in ICP signals.
 
 
 

clc; clear; close all; load icp; icp = icp'; t = 0: (length(icp)-1); t = t/fs; figure(); plot(t, icp); %%Plot ICP in Frequency domain Xf abs (fft (icp)); = finalVal = round (length (Xf)/2); % Take half of Xf values xf = Xf (1: finalval); f = (1: finalVal)-1; % "f" will go from 0-74999 f = f / finalVal; % Last value will be -1 f = f* fs/2; % Last value will be fs/2 and values are equally spaced figure(); plot (f,xf); % Note: You will need to zoom in to see the peaks %%Next step is to filter the signal. % -200th-order "firl" is recommended since IIR filters may % not allow really low cutoff frequencies. To implement the filter, use of "filtfilt" is recommended % over "filter", since "filter" will cause a time-delay in the output signal.
