I have the following code
m=importdata("Raw data (1).csv")
t=m(:,1)
v=m(:,2)
L = length(t);
Ts = t(2)-t(1); % Sampling Interval (sec)
Fs = 1/Ts; % Sampling Frequency
Fn = Fs/2;
Good = v- mean(v); % Remove D-C (Constant) Offset
Y = fft(v)/L;
Fv = linspace(0, 1, fix(L/2)+1)*Fn; % Frequency Vector
Iv = 1:length(Fv); % Index Vector For Plot
figure(1)
plot(Fv, 2*abs(Y(Iv)))
grid
xlabel('Frequency')
ylabel('Magnitude')
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
I would like to integrate the signal. How is this possible ?
