If I have a function z=f(x,y) how do I plot lines of constant y in MATLAB?

Use plot3, define an xvec and yyec with linspace, iterate over length of yvec and plot3(xvec,yvec(k),zfunc(xvec,yvec(k))
keep hold on for the figure window

something like it should work, if you tweak... been a while, but I've done stuff like this.

Ol’ suggested g(x,z)= ιy.(z-f(x,y)=0) where iota is the definite description and it worked because I already knew the domain to look over by other methods. I genuinely thank both of you for all your help!

I don’t know what that is but sounds way more elegant 😄
