Good morning,
My professor is asking is to graph a piecewise function in R3 using anonymous functions and logicals and NOT using if-else statements. He also is asking to use "meshgrid" and the "surf" command. I attached the picture below. How would I start this? Thanks in advance

Start by using meshgrid and surf with a non-piecewise function: find out how to draw a plane at all.
Then use this method:
t = linspace(0, 2*pi, 100);
y = sin(t) .* (t < pi) + cos(t) .* (t >= pi);
plot(t, y)
This is a "logical mask" to create a piecewise function. It works in 2D also.
