Online Matrix Operations Tool
Linear algebra can be tedious. Our Matrix Calculator simplifies the process, allowing you to instantly multiply, add, or subtract matrices. It supports both 2x2 and 3x3 dimensions, making it perfect for students and professionals.
Supported Operations
- Multiplication (A × B): Computes the dot product of rows and columns.
- Addition & Subtraction: Adds or subtracts corresponding elements.
- Determinant: Calculates the scalar value of a square matrix (useful for finding inverses).
- Transpose: Flips the matrix over its diagonal, switching row and column indices.
Why Calculate a Determinant?
The determinant helps us know if a matrix has an inverse. If the determinant is zero, the matrix is "singular" and does not have an inverse. This is crucial for solving systems of linear equations.
Frequently Asked Questions
How do I multiply two matrices?
To calculate the entry in row i and column j of the result, you take the dot product of the ith row of the first matrix and the jth column of the second matrix.
Can I multiply a 2x2 by a 3x3?
No. For matrix multiplication to be valid, the number of columns in the first matrix must equal the number of rows in the second matrix.
