Generate a Unit Matrix

Generate a Unit Matrix (also known as an identity matrix) of any size you choose. Just type in the dimension, and you’ll get a clean matrix with ones on the diagonal and zeros everywhere else. You can format the output as plain text, CSV, or tab-separated with or without brackets.

Options
Wrap rows in brackets
Maximize output

How to Use:

  1. Enter a size in the Matrix Size box (like 3 for a 3×3 identity matrix).
  2. Choose your preferred output format:
    • Plain Text
    • CSV
    • Tab-separated
  3. Toggle “Wrap rows in brackets” to add or remove square brackets.
  4. The matrix appears instantly in the right-hand box.
  5. Click “Copy Output” to copy or “Export to File” to save it.

What Generate a Unit Matrix can do:

It gives you a clean identity matrix of any dimension, from 1×1 up to 100×100. You control the formatting and spacing. It’s great for linear algebra, software testing, or building dummy matrices fast. Output updates live and flashes when changed so you know it’s current.

Example:

Input:Matrix Size: 3Format: Plain TextBrackets: ✓

Output:

[1 0 0]
[0 1 0]
[0 0 1]

Common Use Cases:

Perfect for anyone working with matrix math, needing clean test data, or teaching basic concepts in programming or linear algebra. Whether you want to copy the matrix or save it for later, this tool makes generating unit matrices simple and fast.

Useful Tools & Suggestions:

After generating a unit matrix, Find the Transpose of a Matrix is a good follow-up if you want to flip it for comparison. And if you’re exploring more structure, Calculate Matrix Determinant gives extra insight into how your matrix behaves.
