Kernel Calculator
In linear algebra, one of the most important concepts is understanding solutions to homogeneous systems of equations. These solutions form what is known as the kernel (or null space) of a matrix. Finding the kernel manually can be time-consuming and error-prone, especially for larger matrices. This is where a Kernel Calculator becomes extremely useful.
A Kernel Calculator helps you quickly determine all vectors that satisfy the equation A × x = 0, where A is a matrix and x is a vector. This is widely used in mathematics, physics, computer science, and engineering to analyze systems, transformations, and vector spaces.
Instead of performing complex row reductions manually, this tool provides fast and accurate results, making it ideal for students and professionals alike.
What is a Kernel Calculator?
A Kernel Calculator is a tool that computes the null space (kernel) of a matrix. The kernel consists of all vectors that, when multiplied by the matrix, result in the zero vector.
Mathematically:
Ker(A) = { x | A × x = 0 }
Required Inputs
To use this calculator, you need:
- A matrix (2×2, 3×3, or larger)
- Matrix entries (numbers)
Expected Outputs
The calculator provides:
- Basis vectors of the kernel
- Dimension of the null space
- Simplified solution set
Calculation Logic
The tool works by:
- Converting the matrix into row echelon form
- Applying Gaussian elimination
- Solving homogeneous system A × x = 0
- Expressing free variables as parameters
How to Use the Kernel Calculator
Step 1: Enter Matrix
Input all values of your matrix row by row.
Step 2: Select Size
Choose matrix dimensions (e.g., 3×3).
Step 3: Calculate
Click calculate to process the kernel.
Step 4: View Results

Practical Example
Given matrix:
A =
[1 2]
[2 4]
Solve A × x = 0
Row reduction gives:
x1 = -2×2
So kernel basis is:
(-2, 1)
This means all solutions lie along this vector direction.
