Plotting a point in Matlab

Hello everyone. Do you know how to plot only one point in Matlab? If so, how to change its size?

Thank you so much.

One approach —

x = pi;
y = pi;

figure
plot(x, y, 'p')
grid

figure
plot(x, y, 'p', 'MarkerSize',50)
grid

.

If you just want a single point with an arbitrary size, try plot, and play around with the 'markersize' property. Be sure to specifify a marker (the default marker is none, so a single point won't show up):

plot(1,2,'.', 'markersize', 50)
