Hi,
I am graphing x, y, z equations into surfaces. I am currently doing this in Excel. However, in Excel, I have to use 'matrices' with defined values. How can I graph an equation like this...
x = y + z
...without needing to have defined values/matrices.
How can I do this? Should I stick to Excel? move to MatLab? or is there a better application out there to do this?
Thanks

MATLAB is your tool. Try
[x,y] = meshgrid(0:.1:10);
z = x - y;
mesh(z);
box
mesh is only one of several options you can use to plot data in 3D.

That requires that matrices be defined, which "A" wants to avoid.
