(50g and similia) Matrix Quadric Classification

[d.nicotra]

Hi Hp Museum,
I'm sharing with you an USER-RPL software written by me.
Given a matrix that represent a quadratic form, it will give you the type of surface.
Simply copy files QUADRIC and MINORE to your calculator and put them in the same folder, then put a matrix on the first level of the stack and run QUADRIC. You can get the matrix using the command QXA giving an homogeneous equation in variables X, Y, Z, T.
Have a nice posting!
