Exact input
Enter integers, decimals, or fractions such as −2, 0.5, or 3/4. Copy a matrix as tab-separated text or paste a rectangular block into a cell.
Matrix Calculator
Edit named matrices, combine them with common operations, and keep exact fractional results where possible.
Import data
Paste CSV, tab-separated text, or JSON
Dimension checks
Operations explain incompatible dimensions, singular matrices, non-square inputs, and systems without one unique solution.
Core linear algebra
Use RREF, rank, determinant, inverse, transpose, matrix powers, and linear-system solving in one workspace.
A practical matrix calculator for everyday linear algebra
Matrices can look intimidating at first, especially when you are checking homework, working through a system of equations, or reviewing a technical calculation. This calculator gives you a clear place to enter your values, try an operation, and compare the result with your own work.
Enter matrices the way you already write them
Create a matrix, name it A or B, then edit each cell directly. Whole rows and columns can be pasted from a spreadsheet, and fractions such as 3/4 stay readable instead of being rounded away.
Choose the operation that matches your question
Addition and subtraction compare matrices of the same size. Multiplication combines compatible dimensions, while a scalar multiplies every entry by the same number.
Understand determinant, inverse, and rank
The determinant helps describe whether a square matrix is singular. An inverse is available only when the matrix is non-singular, and rank shows how many independent rows or columns it contains.
Use RREF to see the structure
Reduced row echelon form makes pivots, free variables, and solutions easier to spot. It is also a useful way to check a system of linear equations without losing the intermediate structure.
Useful for study and technical work
Use the workspace for algebra, coordinate transformations, data models, engineering checks, and quick classroom examples. Treat the output as a calculation aid and review important results independently.
