Objectives

- Matrices: operations, power, properties, calculation. Remarkable matrices. Vector space of matrices. Notion of vector subspace. The space Rn seen as the space of matrix-columns.

- Linear systems and pivot method. Space of solutions.

- Determinant in dimensions 2 and 3 - Invertible matrices - Application to linear systems.

- Bases of Rn - coordinates. Intuitive notion of dimension. Change of base - transition matrix.

- Linear applications RpRn. Matrix relative to a base. Change of basis formula.

- Elementary diagonalization (exercises and examples will be limited to the case of 2×2 and 3×3 matrices).

- Application of diagonalization to the solution of linear differential systems.

- (Optional: Matrix exponential. Introduction to non-linear differential systems).
