MS_expand

MS_EXPAND - fill out elasticity matrix.
// Part of MSAT - The Matlab Seismic Anisotropy Toolkit //
Expand a minimal set of elastic constants based on a specifed
            symmetry to a full Cij tensor.
[ Cf ] = MS_expand( C, mode )
Usage:
    Fill out elastic tensor C based on symmetry, defined by mode. This
    can take the following values:
       'auto' - assume symmetry based on number of Cijs specified
       'iso' - isotropic (nec=2) ; C33 and C66 must be specified.
       'hex' - hexagonal (nec=5) ; C33, C44, C11, C66 and C13 must be
               specified, x3 is symmetry axis
       'vti' - synonym for hexagonal
       'cubic' - cubic (nec=3) ; C33, C66 and C12 must be specified
Cijs *not* specified in the appropriate symmetry should be zero in
the input matrix.
