Frequently Asked Questions

Quick answers to common inverse matrix calculator questions.

1. What is an inverse matrix?

An inverse matrix \( A^{-1} \) is a matrix that, when multiplied by \( A \), gives the identity matrix.

2. How do I know if a matrix is invertible?

A matrix is invertible if its determinant is non-zero. Our calculator checks this automatically.

3. Which method does the calculator use?

It uses Gauss–Jordan elimination with partial pivoting for numerical stability.

4. Can I calculate inverses for non-square matrices?

No, only square matrices have true inverses. For non-square matrices, use the pseudoinverse option.

5. What sizes are supported?

We support 2×2 up to 10×10 matrices, with quick presets for common sizes like 3×3 and 4×4.

6. Is my data sent to any server?

No, all calculations run client-side in your browser. Nothing is uploaded or stored.

7. Can I export the results?

Yes, you can copy results as CSV, LaTeX, or share a direct link to your calculation.

8. Will decimals be accurate?

You can adjust the precision (up to 12 decimal places) to balance accuracy and readability.

9. What happens if the matrix is singular?

The calculator will detect it and show a message saying the inverse does not exist.

10. Can I paste data from Excel or Google Sheets?

Yes, you can paste CSV or space-separated values directly into the input grid.

11. Does it support complex numbers?

We have a separate calculator for complex matrix inverses on the site.

12. Can I use it offline?

Yes, once loaded, the calculator runs entirely in your browser without needing the internet.

13. Is this free to use?

Yes, all our matrix calculators are completely free with no sign-up required.

14. Can teachers share results with students?

Yes, the shareable link feature makes it easy to distribute problem sets and solutions.

15. Which browsers are supported?

All modern browsers like Chrome, Edge, Safari, and Firefox are supported.
