Hello, I am very new to this.
I am looking to make a scatter plot with some points plot as black point and some as red according to the indices.
I have a 19 elements array and for the values at indices 2, 4, 6, 9, 13, 15, 16 I want the point to be red and the other ones to be black.
Let A be my 19 elemets array
Let X be my X array
Let indice = [2 4 6 9 13 15 16]
I first wrote this:
scatter(X,A,'*k') and now how can I modify this to get the red points at the proper values?
I guess I need to do a if or for but I am not quite sure how do do this. Can anyone help me out?
