## Matrix Function - MFN: Examples

Matrix Function (MFN) is the object provided by SLEPc for computing the action of a matrix function on a vector. Given a matrix *A* and a vector *b*, the call `MFNSolve(mfn,b,x)`

computes *x=f(A)b*, where *f* is a function such as the exponential.

ex23.c: Computes exp(t*A)*v for a matrix associated with a Markov model

ex26.c: Computes the action of the square root of the 2-D Laplacian

ex37.c: Computes exp(t*A)*v for an advection diffusion operator with Peclet number

ex39.c: Exponential integrator for the heat equation with source term
