Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Edd Barrett (vext0101) Assigned to: Nobody/Anonymous (nobody) Summary: Allow inequalities in augcoefmatrix() Initial Comment: If you give augcoefmatrix() inequalities, maxima does some odd things: augcoefmatrix([a = 1, b >= 1, c <= 2], [a, b, c]); gives: matrix([1,0,0,1],[0,0,0,0>=1],[0,0,0,0<=2]) It would be sweet if maxima could handle these. In the case that the inequalities are mixed, eg, the system conatins a subset of inequalities whose operator are <= (call it R), and another subset whose operators are >= (call them S) you can multiply the coefficients by of one of the inequality types by 1 to arrive at a canonical form. This would work the same for < and > also. It should not be possible to mix >= with >, or <= with > etc. Perhaps not the best explanation, but I hope you know what I am suggesting.
