Question

Ploting real and imaginary numbers in 3D

Hello,

I'm trying to plot the square root of the independent variable x,y. The z variable is the dependent.

Not sure to put it in matrix form or if there is a better way. Also how would it be possible to show real and imaginary numbers.

Thanks.

Yes thank you very much. That worked perfectly. Now also I have a similar example where I tried to graph ln(2x^2+y^2). Its giving the same error as before. I tried using the setup you mentioned previously unable to make it work.

It's a different problem. ln(0) is undefined. Click on the x-axis, and change the lower limit to -9.9 instead of -10. That will make Mathcad miss the 0,0 point that causes the problem.
