Null space calculator

Find a basis for the kernel of a supported matrix.

How to use this calculator

Edit the matrix after kernel. The result describes vectors mapped to zero.

Tap the math below to edit it and see the result. Once a result is ready, press Tab on a hardware keyboard to accept it. Outside a matrix, Return completes the line; the phone math keyboard has the same Return action.

Try it here

kernel⁡([123246])\operatorname{kernel}\left(\begin{bmatrix}1&2&3\\2&4&6\end{bmatrix}\right)

What to know

A basis is not unique; verify that every basis vector satisfies the homogeneous system.

Mathlean combines visual mathematical input with computation and canvas tools. Results depend on the expression and available engine support; check important answers independently.
