HP41C/CV/CX Eigenvalues/Vectors help  mbrethen  02052011 I'm trying to use the "Eigenvalues/Vectors of 3rdOrder for the HP41C/CV/CX" program but get a "divide by zero" error. It looks like the program called “A” sets up matrix "A" so I enter each element, followed with R/S. How is vector "V" entered? Anyone have experience using this program?
Thanks.

EV3X3  for 3x3 matrices, and Data entry is assisted by the program, no issues there.
