The application for calculation of matrices is very useful tool. It is designed for students and engineers who use matrix calculations in their studies or work.

The application perform following operations with matrices:
- Matrix addition
- Matrix subtraction
- Matrix scalar multiplication
- Matrix square
- Matrix multiplication
- Matrix transposition

Determinant calculations:
- Calculation of the determinant using the Sarrus method
- Calculation of the determinant using the Laplace method

Vector operations:
- Vector Length
- Vector coordinates by two points
- Vectors addition
- Vectors subtraction
- Scalar and vector multiplication
- Scalar product of vectors
- Cross product of vectors
- Mixed (scalar) triple product
- Angle between two vectors
- Projection of a vector onto another vector
- Direction cosines
- Collinear vectors
- Orthogonal vectors
- Coplanar vectors
- Area of triangle formed by vectors
- Area of a parallelogram formed by vectors
- Volume of pyramid formed by vectors
- Volume of a parallelepiped formed by vectors

System of linear equations:
- System of linear equations, substitution methods
- System of linear equations, Cramer's methods
- System of linear equations, invertible matrix method

The application is localized into 8 languages.
The application displays step by step calculations. You can calculate matrix with dimensions up to 5x5 and vectors in 2d/3d. It also includes a random numbers generator for fast creating matrices and vectors with random numbers.
The application is being actively developed and supplemented with new calculators. Keep for updates!
