What is an Identity Matrix?
An identity matrix is a square matrix in which:
- All diagonal elements are 1
- All non-diagonal elements are 0
For example, a 3×3 identity matrix looks like this:
1 0 0
0 1 0
0 0 1
It plays a crucial role in mathematics, especially in:
- Matrix multiplication
- Linear transformations
- Computer graphics
- Engineering calculations
Practical Examples of the Identity Matrix Calculator
Example 1: 3×3 Identity Matrix
If you enter 3, the tool generates:
1 0 0
0 1 0
0 0 1
This is commonly used in basic algebra and educational exercises to understand matrix structure.
Example 2: 5×5 Identity Matrix
If you enter 5, the output becomes:
1 0 0 0 0
0 1 0 0 0
0 0 1 0 0
0 0 0 1 0
0 0 0 0 1
This is useful in advanced mathematics, computer science algorithms, and simulations.
