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 ?
