Integer Matrix Power Calculator
Integer Matrix Power with stated conventions, validation and a worked example.
Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Real matrices only, at most 6 rows and 6 columns; each entry has magnitude at most 10⁹. Numerical rank uses a relative pivot threshold of 10⁻¹² after scaling by the largest entry. Near-singular matrices may be rejected or treated as lower rank. Displayed entries use 12 significant digits. Negative or fractional powers are not included.
Example Calculation
- Square matrix: 1, 1; 0, 1
- Nonnegative exponent: 3
[[1,1],[0,1]]³ = [[1,3],[0,1]].

Frequently asked questions
How do I use this calculator?
Enter square matrix, nonnegative exponent. The result updates automatically. Use Reset to restore the example values.
What method does it use?
A⁰=I; use repeated squaring for Aⁿ.. Real matrices only, at most 6 rows and 6 columns; each entry has magnitude at most 10⁹. Numerical rank uses a relative pivot threshold of 10⁻¹² after scaling by the largest entry. Near-singular matrices may be rejected or treated as lower rank. Displayed entries use 12 significant digits. Negative or fractional powers are not included.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
