How to plot a value as function of two variables

Hello,

I would like to plot the value of a function as function of two variables. Example : [x y] => Value

The value could be manifested by a change of color, as it would be if it was a surface. The only difference is that I want to plot it as a 2D graph.

Thank you very much,

Max

Hello,

I found this other question which is similar. I would have prefer a continuous line, rather than dots, but I'll keep this solution. Except if you find a better one ;)

How about plot3(x,y,z)?

Hello,

I just tried plot3(x,y,z), it returns a 3D plots with 3 axis. Whereas I would like only 2 axis.

Thanks,
