The nonlinear operator is written as T(lambda) = sum_i A_i*f_i(lambda),
for i=1,...,n. The derivative T'(lambda) can be obtained using the
derivatives of f_i.
<P>
The structure flag provides information about A_i's nonzero pattern
(see MatStructure enum). If all matrices have the same pattern, then
use SAME_NONZERO_PATTERN. If the patterns are different but contained
in the pattern of the first one, then use SUBSET_NONZERO_PATTERN.
Otherwise use DIFFERENT_NONZERO_PATTERN.
<P>
This function must be called before <A HREF="../NEP/NEPSetUp.html#NEPSetUp">NEPSetUp</A>(). If it is called again
after <A HREF="../NEP/NEPSetUp.html#NEPSetUp">NEPSetUp</A>() then the <A HREF="../NEP/NEP.html#NEP">NEP</A> object is reset.
