Determinant

Function: determinant (<M>) Computes the determinant of <M> by a method similar to Gaussian elimination.

A:matrix([5*s+8,4],[4,12]);
dA:determinant(A);
B:matrix([5*s+8,4],[(24/S)+15,24/S]);

The form of the result depends upon the setting of the switch ratmx.

There is a special routine for computing sparse determinants which is called when the switches ratmx and sparse are both true.

(%o1)                                true
(%i2)
