Question 1

What is a Null Space Calculator?

Accepted Answer

The null space (kernel) of a matrix A is the set of all vectors x such that Ax = 0. The nullity is the dimension of the null space. Understanding null space is essential in solving linear systems and linear algebra.

Question 2

How does the Null Space Calculator work?

Accepted Answer

Solve Ax = 0 using row reduction (RREF) Then: Free variables correspond to null space dimensions Then: Rank-nullity theorem: rank + nullity = n (columns) Then: Null space is always a subspace containing the zero vector.

Question 3

Can you give an example of how to use the Null Space Calculator?

Accepted Answer

Example: Input [[1,2,3],[4,5,6]] × x = 0 gives a result of Null space has dimension 1; one free variable.
