Simple and to the point! Great video.

Great video! I did not understand the objective of xx and yy. They are just repeating the points 20 times, am I correct?

[@2010aurnob]

are you creating the meshgrid to have a surface for the surface plot?

[@CarlosMontalvo251]

yup you got it. x and y are just vectors but xx and yy are matrices

[@vstechkythuat]

can you share your code for me, I need your method for my problem? thank you
