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) Then Octave will output an answer saying

ans=50
