initialized to zero, as are new entries in matrices and arrays after resizing. Not defined by default.
- \b EIGEN_INITIALIZE_MATRICES_BY_NAN - if defined, all entries of newly constructed matrices and arrays are
initialized to NaN, as are new entries in matrices and arrays after resizing. This option is especially
useful for debugging purpose, though a memory tool like <a href="http://valgrind.org/">valgring</a> is
preferable. Not defined by default.
- \b EIGEN_NO_AUTOMATIC_RESIZING - if defined, the matrices (or arrays) on both sides of an assignment
<tt>a = b</tt> have to be of the same size; otherwise, %Eigen automatically resizes \c a so that it is of
the correct size. Not defined by default.
