HP Prime: Linear Solver app bug
Message #1 Posted by BruceH on 15 Nov 2013, 6:36 p.m.

Start the Linear Solver App. Enter a 3*3 set of equations. Solve if you like. Now touch the 2 variable button on the screen. The 3rd equation vanishes, the Z's and their coefficients vanish from the first 2 equations, but the remaining coeffiicents are unchanged. OK, that's what I would expect.

Now go back to the 3 variable mode. The 3rd equation reappears, unchanged. But the coefficients of Z in the first 2 equations are set to 0. If you do not notice this you can get some crazy answers.
