computing the nullspace
(2.8 hours to learn)
The nullspace of a matrix can be computed using Gaussian elimination.
This concept has the prerequisites:
- column space and nullspace
- Gaussian elimination (Gaussian elimination is used to compute the nullspace.)
- Be able to compute the basis for the nullspace using Gaussian elimination
