Determinant

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

a:matrix([a1,a2,a3],[b1,b2,b3],[c1,c2,c3]);
determinant(a);

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)
