How to use this tool
A quick workflow so you can get the result you need without guesswork.
- 1
Enter one matrix per box using spaces or commas between values and a new line for each row.
- 2
Choose an operation such as multiply, add, subtract, transpose, determinant, or inverse.
- 3
Run the calculation to see the result matrix or scalar output along with shape information.
Useful examples
Practical cases where this utility saves time and reduces mistakes.
Data and graphics work
Developers can test transformation matrices, covariance examples, and small numeric workflows quickly in the browser.
Teaching and demos
Tutors can paste sample matrices and explain row-column multiplication without switching to a separate desktop app.
Frequently asked questions
Short answers to the most common questions about the calculator above.
How should I format a matrix?
Use one row per line and separate values with spaces or commas. For example: 1 2 3 on the first line and 4 5 6 on the second line.
Can this matrix calculator invert any matrix?
It can invert square matrices that have a non-zero determinant. Singular matrices do not have an inverse and the tool will report that clearly.
Which operations require both matrices?
Addition, subtraction, and multiplication use both matrix A and matrix B. Determinant, transpose, and inverse operate on the selected single matrix.
Does this tool support decimals?
Yes. You can enter integers or decimals, and the calculator will return decimal results when needed.
Perform Common Matrix Operations Online
This free matrix calculator handles the matrix operations most people need in a browser: addition, subtraction, multiplication, transpose, determinant, and inverse. It is designed for small to medium matrices that you want to test quickly without opening a specialized math package.
Each calculation runs locally in JavaScript, so you can work through examples, class exercises, and transformation problems with immediate feedback. The result panel also reports the shape of the output, which helps catch dimension mistakes early.
Useful for Algebra, Graphics, and Numeric Prototyping
Matrices show up in linear algebra, machine learning, graphics, simulations, and systems of equations. A lightweight online matrix calculator is especially helpful when you need to validate one step of a derivation rather than spin up a notebook or larger environment.
Whether you are multiplying two matrices, checking whether a square matrix is invertible, or confirming a determinant by hand, this page is built for clear input and fast iteration.
