Here Are Some Linear Algebra Functions You Can Use In Octave
- balance (Eigenvalue Balancing)
- cond (Condition Number)
- dmult (computes diag(x)* A efficently)
- dot (Dot Product)
- orth (Orthonormal basis of the range space)
- pinv (pseudoinverse)
- det (Determinant)
For Example when solving a simple matrix to find its determinant you:
A=[2,0,0;0,5,0;0,0,5;]
| 2 0 0 |
| 0 5 0 |
| 0 0 5 |
det (A)
ans=50
