## 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.

test1.c: Computes exp(t*A)*v for a matrix loaded from file
test2.c: Tests the case when both arguments of MFNSolve() are the same Vec
test3.c: Test MFN interface functions
test4.c: Illustrates use of MFNSetBV()
