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

Ran in:
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)
