About this app

The application for calculating matrices, determinants, and vectors is a very useful tool. It is designed for students and engineers who rely on matrix calculations in their studies or work.
Using the necessary formulas, the program performs step-by-step calculations and provides a detailed solution. You can calculate matrices with dimensions up to 5x5 and vectors in 2D or 3D. Each calculator includes a brief theoretical explanation of the specific task.
The application also features a random number generator to quickly create sample expressions with random numbers.

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

The application content is available in the following languages: English, French, German, Italian, Portuguese, Russian, Spanish, and Ukrainian.
The application is being actively developed and supplemented with new calculators. Keep for updates!

Ratings and reviews

Doesn't work past three columns or three rows. You are stuck with a 3×3 grid. You fill in the 4th row or column, it places that number in the 3rd column. One star.

When transposing a matrix, it sometimes squashes adjacent rows into the same cells. Haven't checked out all calculations, but this was enough - unistalling

Good program for homework :)

What’s new
