matlab: scatter plots with high number of datapoints

Question

I\'m trying to plot scatter, something like:

scatter(coor(:, 2), coor(:, 3), 1, coor(:, 4));

The problem is, that I have quite big number o

Answer 1

Yes, use plot3

plot3(coor(:, 2), coor(:, 3), coor(:, 4), '.')

This will do the same as a 3d scatter plot (the points will be small dots, you can also use 'o' or 'x' if you want)
