Plotting points while plotting vectors : Matlab

Question

I need to make a plot with only points and tried something like

plot(x,y)

where x and y are vectors: collection of points.

I do not want matlab to connect these points itself. I want to plot as if plotted with

for loop
plot;hold on;
end

I tried

plot(x,y,'.');

But this gave me too thick points.

I do not want to use forloop because it is time expensive. It takes a lot of time.

Answer 1

You're almost there, just change the MarkerSize property:

plot(x,y,'.','MarkerSize',1)

Answer 2

Try:

plot(x,y,'*');

or

plot(x,y,'+');

You can take a look to the documentation: http://www.mathworks.nl/help/matlab/creating_plots/using-high-level-plotting-functions.html
