Hi everyone, I face a difficulty in plotting graph from mat file. I want to get the graph from the mat file but the graph did not pop out and get the result in command window as shown in the figure 1 below.
Figure 1
The figure 2 below is the setting for the code.
Anyone can help me? Thanks. This is the code I am using:
clc;
clear all;
close all;
s = load('lai3.mat');
plot(transpose(s.val))

clc;
clear all;
close all;
s = load('lai3.mat');
x=s.lai3(:,1); % s is having a field named lai3
y=s.lai3(:,2);
plot(x,y)

It is the naming of my file. I put graph.mat instead of other name. That's why have the problem.
