Input1 = load('double_lane_velocity_lane1.txt');
Input2 = load('double_lane_velocity_lane2.txt');
figure
for ii = 0:49
index1 = find(Input1(:,1)==ii);
index2 = find(Input2(:,1)==ii);
t = [Input1(index1,2); Input2(index2,2)];
In = [Input1(index1,3); Input2(index2,3)];
plot(t,In),hold on
end
ylim([18 41])
xlabel('Simulation Time (s)')
ylabel('velocity (m/s)')

thanks very much, is there anyway to graph each text file seperately? double_lane_velocity_lane1 is what you have graphed and it does look exactly as it is meant to but double_lane_velocity_lane2 looks a little different.
also ive attached another two text files i was wondering if you could tell me why your code doesnt work for these? thank you very much i appreciate your help

For plotting combined input 1 and 2
clear, clc, close all;
Input1 = load('double_lane_position_lane12k.txt');
Input2 = load('double_lane_position_lane22k.txt');
fig = figure;
for ii = 0:49
index1 = find(Input1(:,1)==ii);
index2 = find(Input2(:,1)==ii);
t = [Input1(index1,2); Input2(index2,2)];
In = [Input1(index1,3); Input2(index2,3)];
plot(t,In),hold on
end
xlabel('Simulation Time (s)')
ylabel('velocity (m/s)')
you can edith this code for plotting input 1 and 2 seperate
