surf Draws a solid surface.
[X,Y] = meshgrid(-2:.1:2, -2:.1:2);
surf(X, Y, sin(pi*X).*cos(pi*Y))
text Annotates a figure, by placing text at specified coordinates.
text(x, y, 'string')
title Assigns a title to the current figure window.
title 'Nice Picture'
xlabel Assigns a label to the horizontal coordinate axis.
xlabel('Year')
ylabel Assigns a label to the vertical coordinate axis.
ylabel('Population')
view Specifies a point from which to view a 3D graph.
ezsurf('(xˆ2 + yˆ2)*exp(-(xˆ2 + yˆ2))'); view([0 0 1])
syms x y; ezmesh(x*y); view([1 0 0])
zoom Rescales a figure by a specified factor; zoom by itself enables use of the mouse
for zooming in or out.
