Basis Of Kernel Calculator
In linear algebra, understanding the kernel (null space) of a matrix is essential for solving systems of equations, transformations, and vector space analysis. The Basis of Kernel Calculator on our website helps you quickly find the basis vectors of the kernel of a matrix.
This tool is especially useful for students, engineers, and researchers working with linear transformations and matrix equations.
What Is a Basis of Kernel Calculator?
A Basis of Kernel Calculator is an online tool that determines all vectors that satisfy:
A × x = 0
Where:
- A = matrix
- x = vector
- Kernel = all solutions that map to zero
The tool then extracts a basis, which is the smallest set of independent vectors that span the kernel.
Required Inputs
To calculate the kernel basis, the tool requires:
1. Matrix Input
- Rows and columns of a matrix
- Example: 2×2, 3×3, or larger matrices
2. Linear System Values
- Coefficient values inside the matrix
Outputs You Get
After calculation, the tool provides:
- Kernel (null space) vectors
- Basis vectors of the kernel
- Dimension of null space
- Step-by-step reduction (optional view)
Calculation Logic Explained
The kernel is found by solving:
Main Equation:
A × x = 0
Steps Used:
- Convert matrix into row echelon form
- Apply Gaussian elimination
- Identify free variables
- Express solution in vector form
- Extract independent basis vectors
Example:
Matrix A:
[1 2 3]
[2 4 6]
After reduction:
- One independent equation remains
Kernel basis:
- (-2, 1, 0), (-3, 0, 1)
