RE: GRAPH 3D v2.2 (beta)
Hi John,
You are likely seeing that message because the routine that generates the z-values are likely running into instances where the input values are just right and end up causing an evaluation error. For example, \( \displaystyle 1-\frac{\cos(x^2+y^2)}{x^2+y^2} \) has a singularity at \( x=y=0 \). So when you use an even-sized grid, then you will have a domain error. You can get a bigger wireframe by using an odd integer (e.g. 49) or changing the window so that it isn't perfectly symmetric. Graph 3D | QPI | SolveSys |
