Question

figure;
plot(trainingSet(:, 1), trainingSet(:, 2), '*');
figure;
plot(reprVectors(:, 1), reprVectors(:, 2), '*');

How do I plot the points from trainingSet and reprVectors in same figure instead of 2 different ones?

Also How can I make trainingSet pts blue and reprVectors points red?

Answer 1

What you describe is the subplot function: same figure, different plot axes

eg:

c=-2:0.1:2;
figure
subplot(121)
plot(x,x);
subplot(122)
plot(x,x.^2)

This plots the function y=x and y=x^2 in one figure, but next to eachother.

The red/blue and marker options are already explained in other answers 🙂
