Find Matrix Inverse

If you’ve got a square matrix and you want the inverse fast, this does the job. Just paste it in rows separated by line breaks, values by commas and boom, the inverse pops right up. It handles 2×2, 3×3, whatever you throw at it (as long as it’s invertible). You’ll see a live preview, and you can copy or export the result without any fuss.

Paste your matrix above or import a file below.

How to Use:

  1. Enter your matrix into the input box on the left. Use commas to separate values and newlines for rows (e.g., 1,2 3,4).
  2. Alternatively, click Choose File to import a .txt, .csv, or .json file.
  3. The inverse matrix appears instantly in the right-hand output box.
  4. Click Copy Output to copy the matrix.
  5. Choose Export to File to download the result.
  6. Select Clear All to reset the fields and input a new matrix.

What Inverse Matrix Tool can do:

Inverse Matrix Tool takes a square matrix and calculates its inverse using JavaScript’s math.js library. The matrix must be invertible (non-singular). If the matrix is invalid or non-invertible, the tool notifies you right away. With live updates, file import support, and clear formatting, it’s a quick way to find inverses without needing a spreadsheet or a symbolic calculator.

Example:

Input:

1,2
3,4

Output:

-2,1
1.5,-0.5

Common Use Cases:

Perfect for quick math checks, working with systems of equations, or throwing together test data for matrix-based functions. Whether you’re coding, studying, or debugging some matrix logic, this saves you time no more wrangling with formulas or writing your own inverse calculator.

Useful Tools & Suggestions:

If you’re working with matrix inverses, Calculate Matrix Determinant helps you know if the inverse even exists. And once you’ve got that sorted, Visualize a List can be useful for breaking down matrix values element by element.
