What is a Matrix Calculator?
A matrix calculator is a specialised tool for performing operations on matrices, which are rectangular arrays of numbers arranged in rows and columns. Matrix calculations are fundamental in linear algebra, computer graphics, engineering, and many other fields.
Our matrix calculator supports essential matrix operations including addition, subtraction, multiplication, finding the inverse, calculating the determinant, and more. It's perfect for students studying linear algebra, engineers working with transformations, and anyone who needs to perform matrix calculations.
Common Matrix Operations
Matrix Addition & Subtraction
Add or subtract two matrices of the same dimensions by adding or subtracting corresponding elements.
Matrix Multiplication
Multiply two matrices where the number of columns in the first matrix equals the number of rows in the second matrix.
Inverse Matrix
Find the inverse of a square matrix, which when multiplied by the original matrix gives the identity matrix.
Determinant
Calculate the determinant of a square matrix, a scalar value that provides important information about the matrix.
How to Use the Matrix Calculator
- Select matrix size: Choose the dimensions (rows × columns) for your matrices.
- Enter values: Input the numbers for each matrix element in the appropriate cells.
- Choose operation: Select the operation you want to perform (addition, multiplication, inverse, etc.).
- Calculate: Click the calculate button to get your result.
- View result: The result matrix will be displayed, or an error message if the operation is not possible.
Frequently Asked Questions
What is the maximum matrix size I can use?
Our calculator supports matrices up to reasonable sizes for educational and professional use. Very large matrices may take longer to process.
Can I multiply any two matrices?
No, matrix multiplication is only possible when the number of columns in the first matrix equals the number of rows in the second matrix. For example, a 2×3 matrix can only be multiplied by a 3×n matrix.
What is a matrix inverse?
The inverse of a matrix A is another matrix (denoted A⁻¹) such that when multiplied together, they produce the identity matrix. Only square matrices with a non-zero determinant have an inverse.
Is this calculator free to use?
Yes, our matrix calculator is completely free to use with no registration required. You can perform unlimited matrix calculations.
