Let me ask here, since there are many very smart people here.
I am reviewing matrix arithmetic and linear algebra and I am struggling with gnuplot to visualize 3d planar geometry and it just doesn't work well. Any suggestions for a different tool or a hint on how to make gnuplot take and map equations like 3x-2y+5z = 13, 2x -14y -3z = 6, and 5x+8y-12z=144
And to quickly plot them to see what they look like and how they intersect?
Solve for z and use splot: splot (3*x-2*y-13)/-5, + (2*x-14*y-6)/3, + (5*x+8*y-144)/12
that is too tedious. I want to visualize all the planes as one manipulates a matrix of equations as one adds them and subtracts them when solving simultaneous equations.. I am surprised this is so hard in 2024..
What about octave? IIRC it should be closer to systems like wolfram
I haven't used wolffram yet. I was looking at it yesterday and I couldn't get it to make two planes on the same graph. I sort of then decided to post this message. I will try octave. For years I have been trying to understand linear algebra and vector math. I can curse Gilbert Strang. I can't understand a thing he does.
