Android Giveaway of the Day - Matroid

Matroid is the first application of matrices for Android that allows you to:

»Add, subtract and multiply matrices.
»Calculate determinants, ranges and inverse matrices.
»Eliminate rows and columns linearly dependent on a matrix.
»Solve determined and indeterminate systems of linear equations, obtaining their solutions according to parameters if necessary.

And all this, always working with fractions or with decimals (both of arbitrary precision), to suit the user, to obtain results as accurate as desired.
In addition, Matroid does not impose restrictions of any kind on the dimensions of the matrices to be calculated.

This application is in continuous evolution, and it is foreseen in future updates the calculation of characteristic polynomials, as well as of eigenvalues.
