How do I load and plot the .mat file

How do I plot it out? Thank you for anyone who can help

[Mathieu NOE]

hello

I got no data when loading - empty mat file ??

[Junzhen Liu]

Sorry, can you check this one?

This cannot work:

load('A1S1.mat', '_1_Time')

Names of variables cannot start with an underscore.

What is the contents of the mat file?

data = load('A1S1.mat')

Sorry, I just update the file, can you check again?

This is one way:

S = load('lab31part1.mat');

t = S.lab3_part1_Time;
v = S.lab3_part1_Value;

subplot(2,1,1)
plot(t(:,1),v(:,1))
grid on
subplot(2,1,2)
plot(t(:,2),v(:,2))
grid on

Or if you want them in the same axes:

clf % just to reset web-plot
S = load('lab31part1.mat');
t = S.lab3_part1_Time;
v = S.lab3_part1_Value;

plot(t,v)
grid on
