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: permanent (<M>, <n>) Computes the permanent of the matrix <M>. A permanent is like a determinant but with no sign changes.
