Tasks of Linear Algebra
We will consider the following tasks:
- Solve Ax = b, given A and b.
- Solve Axi = bi for multiple bi's.
- Calculate A-1, where A-1A = I, the identity matrix.
- Calculate determinant of A, det(A).
Large packages of routines available for these tasks, e.g. LINPACK, LAPACK (public domain); IMSL, NAG libraries (commercial).
We will look at methods assuming n = m.
