Resolution of linear systems:
• Direct methods.
• Iterative methods.
• Descente method and conjuguate gradient.
• Linear system with structured matrices (Toeplitz, Hankel, Vandermonde or Cauchy):
- Circulating Matrices.
- Relations between structured matrices and polynomials and fast algorithms associated to polynomials.
- Fast multiplication of a structured matrix by a vector.
- Fast resolution of structured system.
