I have a signal and respective time ,how shall I cut it at a certain more or less close to tol value/time vector value.

How to set the tol and plot the cut signals ?

close all
clear all
load signal
load t
S = signal(1,:);
tol = 0.5/2310;
plot(t,S);
T = (1:tol); %??
%then plot limited signal with limited time

plot(t,S);
[minDistance, indexOfMin] = min(abs(tol-t));
newt = t(1:indexOfMin);
newS = S(1:indexOfMin);
plot(newt,newS);

Hey ,

for a project i have to generate a sinusoidal signal(force signal) and a second signal with a step function(speed signal) , then try to get the amplitude of the force signal and the phase difference to the speed signal. In which i have to cut the force signal in time domain in the same time of the step of the speed signal , and then show the amplitude and phase at that point using FFT. any Ideas ?
