Hello I want to use 'x' or 'o' in the plot regarding the value of each elemants in T.
so if point (1,3) is labeled with 0, I'll put 'o'
if point (1,3) is labeled with 1, I'll put 'x'
if point (1,3) is labeled with 2, I'll put 'r'
How can that be possible?
clc;clear;
data = load('test_data.txt');
sample_size = size(data,1);
X=[ones(sample_size,1) data(:,1) data(:,2)]';
T = data(:,3)';
plot(X(2,:),X(3,:),'x', 'MarkerFaceColor', [0.2, 0.2, 0.5], 'MarkerEdgeColor', 'k', 'MarkerSize', 7)
title('Plot of test data')
grid on;
xlabel('x1');
ylabel('x2');
