Matrix Inverse Calculator: Complete Guide
What Is It?
A matrix inverse calculator is a digital tool that automatically calculates the multiplicative inverse (A⁻¹) of a square matrix A, where A × A⁻¹ = I (identity matrix). It handles complex calculations instantly, providing:
- Precise numerical results
- Step-by-step solution methods
- Visual matrix comparisons
- Determinant verification
Key Formula
The inverse is calculated using:
Where:
det(A)= determinant of matrix Aadj(A)= adjugate matrix of A
How to Use

FAQs
Q: Which matrices can be inverted?
A: Only square matrices with non-zero determinants (non-singular)
Q: Why does my matrix show “singular” error?
A: This means its determinant is zero (e.g., linearly dependent rows)
Q: How precise are the calculations?
A: Configurable up to 8 decimal places
Q: Can I invert complex number matrices?
A: This version handles real numbers only
