Matrix Determinant (v. 3.1)

Georg Kiefer опубликовал приложение 2013-01-02
(обновлено 2015-03-26)

This mathematical app is able to calculate the determinant of a matrix. The determinants of following matrices can be computed:
- 2x2 matrices
- 3x3 matrices
- 4x4 matrices
- 5x5 matrices
- nxn matrices (with more than 5 rows and columns)

In linear algebra, the determinant is a value associated with a square matrix. The determinant provides important information when the matrix is that of the coefficients of a system of linear equations, or when it corresponds to a linear transformation of a vector space.

This free app is ad supported and may contain ads in the notification tray and/or home screen.

Matrix Eigenvalues (v. 2.0)

Matrix Eigenvalues is a mathematical app, which calculates
the eigenvalues and eigenvectors of a given matrix.

The following matrices are available:
2x2 matrices
3x3 matrices
4x4 matrices
5x5 matrices
nxn matrices (more than 5 rows and columns)

An eigenvector of a square matrix A is a non-zero vector v that, when multiplied by the matrix yields the original vector multiplied by a single number.
The number  is called the eigenvalue.

Eigenvalues and eigenvectors have many applications in both pure and applied mathematics. They are used in matrix factorization, in quantum mechanics, and in many other areas.
