Matlab for Non Believers - 3D Surface Plots

Here's a description of two easy ways to make surface plots in Matlab, including step-by-step instructions.

You could also do [x, y]=meshgrid(-4:0.1:4) :)

Hi, Thank you for your elaborative explanation, i've a question, how can we make a surface for two perpendicular functions? for example, I've a linear function between Z and X, and an exponential function between Z and Y, how would be able to create a surface between these two perpendicular plans? and thank you again!

great video!
How about when you do not have a function but you have a table with the data instead.

thanks for the video. Please I want to plot a 3D surf of two equations united by ‘if’ and ‘else’ statements. For example. “if X>Y Z=2X+Y elseif X<=Y Z=3X-2Y end surfc(X, Y, Z)” …. How do I go about it? Thanks in advance.

Hi. What if we want the same 3D graph upside down. The one which is obtained at time 4:00 in the video.

Hi Mark, I would like to ask you about: how could i create isosurfaces in a 3d cube when we have x, y, z (coordinates) and a volumen value v..? Thanks in advance!

In matlab 2022a that command "surf(X, Y, F)" gets an error. Would you please help me figure it out how it can be fixed? Thanks.
