Hello Gun Gu,

You can use surf function to do that plot.

Here is the link: surf

Also you can look at below function in fileexchange (Create your x and y vectors, calculate your z with the function you have given). Call vecsurf with 3 vectors, x,y,z.

Demo 6 and 7 suits for your case.

Here is the link: vecsurf
