Online Algebra Calculator
Many of users do not use powerful Maxima computer algebra system for systematic work, but for ad hoc algebraic calculations – equations, functions, matrixes, etc. only. To do this job, it is not useful to download the whole application from a web site.
Function: determinant (<M>) Computes the determinant of <M> by a method similar to Gaussian elimination.

m:matrix([1,1],[1,-1]);
n:transpose(m);
n:n*determinant(m);

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.
