<h2>Matrix Function - MFN: <a href="../../../src/mfn/examples/tutorials/index.html">Examples</a></h2>
<p>
Matrix Function (MFN) is the object provided by SLEPc for computing the action of a matrix function on a vector. Given a matrix <i>A</i> and a vector <i>b</i>, the call <code>MFNSolve(mfn,b,x)</code> computes <i>x=f(A)b</i>, where <i>f</i> is a function such as the exponential.
