CalcMatr

Integer and fractional elements are allowed, but not floating point numbers.
Matrices (or their elements) and systems of linear equations can be also generated by the app, to practice with operations and propieties.
The app calculates the matrix range, determiner of square matrices, traspose, inverse of inversible matrices (that is,
square matrices with non zero determiner), the matrix of adjuncts, the forms of Gauss and Gauss-Jordan.
It allows submatrices extraction by selection of rows and columns.
Combined operations among matrixes: addition, subtraction, product, raising to a power
Systems of equations up to 4 equations with 4 unknowns, also introduced by the user or generated by the app: it makes the classification of the system and the resolution in consistent systems.
