CalcMatr

With this app you can work with matrices and systems of linear equations of integer or fractional coefficients.

They can be introduced by the user, so that you can solve your own problems, or generated by the app, and then you can practice with properties and operations. The matrices introduced or generated are always visible and available for calculations and operations.

Calculations an operations with matrices are:
- The matrix range
- Determiner of square matrices
- Traspose of a matrix
- Inverse of inversible matrices (square matrices with non zero determiner)
- Matrix of adjuncts
- Gauss and Gauss-Jordan.
- Submatrices extraction by selection of rows and columns.
- Product of a matrix by a number
- Raise to a power.    
- Combined operations (addition, subtraction, product, raising to a power, if they are possible) with two or more matrices.    
    
Systems of linear equations of up to 4 equations with 4 unknowns:
The system is classified (in consistent, dependent or inconsistent) and solved when consistent. It can be saved in a file.

In short, this is an useful tool for common exercises involving matrices and systems of linear equations.
