Finding orthogonal basis for the nullspace of a matrix?

Click For Summary
SUMMARY

The discussion focuses on finding an orthogonal basis for the nullspace of the matrix [[2, -2, 14], [0, 3, -7], [0, 0, 2]]. The nullspace of this matrix is determined to be the set containing only the zero vector, x = [0, 0, 0]. Since the nullspace consists solely of the zero vector, any orthogonal basis can be represented by this vector, confirming that the solution is complete with no additional vectors required.

PREREQUISITES
  • Understanding of linear algebra concepts, particularly nullspace and orthogonal basis.
  • Familiarity with matrix representation and operations.
  • Knowledge of vector spaces and their properties.
  • Basic proficiency in solving linear equations and systems.
NEXT STEPS
  • Study the properties of nullspaces in linear transformations.
  • Learn about orthogonal projections and their applications in vector spaces.
  • Explore the Gram-Schmidt process for generating orthogonal bases.
  • Investigate the implications of nullspace dimensions in relation to rank-nullity theorem.
USEFUL FOR

Students studying linear algebra, educators teaching matrix theory, and anyone interested in understanding vector spaces and their properties.

Find an orthogonal basis for the nullspace of the matrix

[2 -2 14]
[0 3 -7]
[0 0 2]

The Attempt at a Solution



The nullspace is x = [0, 0, 0], so what is the orthogonal basis? It can be anything can't it?

The nullspace (or kernel) of this matrix is {(0, 0, 0)}. The zero vector is the only vector in this set, so you're done.
