MATLAB meshgrid, surf, and mesh 3D plotting

MATLAB 3D plotting.
view(2) and view(3) commands for going from 2 to 3D views.

Creating a meshgrid for the foundation of surface plots and mesh plots.

such an underrated video, better than my damn university professor teachings 😂

this is world class!!! thank you soo much

Thanks for the video! Question: Once I have a 3D surface, is there any way to interpolate to find a Z value based on an X1 and X2 values that dont have a Z value defined? In my case, Z is not based on a formula.

Hello there, thanks for the great video!
I have a similar program that I need to do in MATLAB.
I have around 100 rows of X, Y, Z points as a data file, to be considered as a matrix.
And 100 rows in 1 column of binary data, as a vector.
I need to slice the 100 rows of xyz matrix data, with the vector data to obtain a 3D model.
Could I contact you in person, maybe an email, regarding this problem?
I do have a rough code, but would like if I get some help from someone who's well versed in MATLAB.

I love the explanation, it's so clear!
Anyway could you help me to draw a 3d graphs but rather different than these one on video. My data is of the format (x, y, z, T), where x, y and z are axes indicating a point and T is the colour value at the specified point. I'm so thankful if you could make video to solve my problems, thanks in advance!

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.
