r"""
Compute force field kernel matrix.
The Hessian of the Matern kernel is used with n = 2 (twice
differentiable). Each row and column consists of matrix-valued blocks,
which encode the interaction of one training point with all others. The
result is stored in shared memory (a global variable).
Parameters
----------
R_desc : :obj:`numpy.ndarray`
Array containing the descriptor for each training point.
R_d_desc : :obj:`numpy.ndarray`
Array containing the gradient of the descriptor for
each training point.
tril_perms_lin : :obj:`numpy.ndarray`
1D array containing all recovered permutations
expanded as one large permutation to be applied to a
tiled copy of the object to be permuted.
sig : int
Hyper-parameter :math:`\sigma`(kernel length scale).
use_E_cstr : bool, optional
True: include energy constraints in the kernel,
False: default (s)GDML kernel.
callback : callable, optional
Kernel assembly progress function that takes three
arguments:
current : int
Current progress (number of completed entries).
total : int
Task size (total number of entries to create).
done_str : :obj:`str`, optional
Once complete, this string contains the
time it took to assemble the kernel (seconds).
cols_m_limit : int, optional
Only generate the columns up to index 'cols_m_limit'. This creates
a M*3N x cols_m_limit*3N kernel matrix, instead of M*3N x M*3N.
cols_3n_keep_idxs : :obj:`numpy.ndarray`, optional
Only generate columns with the given indices in the 3N x 3N
kernel function. The resulting kernel matrix will have dimension
M*3N x M*len(cols_3n_keep_idxs).
Returns
-------
:obj:`numpy.ndarray`
Force field kernel matrix.

Compute force field kernel matrix.
The Hessian of the Matern kernel is used with n = 2 (twice
differentiable). Each row and column consists of matrix-valued blocks,
which encode the interaction of one training point with all others. The
result is stored in shared memory (a global variable).
Parameters
----------
R_desc : :obj:`numpy.ndarray`
Array containing the descriptor for each training point.
R_d_desc : :obj:`numpy.ndarray`
Array containing the gradient of the descriptor for
each training point.
n_perms : int
Number of individual permutations encoded in
`tril_perms_lin`.
tril_perms_lin : :obj:`numpy.ndarray`
1D array containing all recovered permutations
expanded as one large permutation to be applied to a
tiled copy of the object to be permuted.
sig : int
Hyper-parameter :math:`\sigma`(kernel length scale).
use_E_cstr : bool, optional
True: include energy constraints in the kernel,
False: default (s)GDML kernel.
progress_callback : callable, optional
Kernel assembly progress function that takes three
arguments:
current : int
Current progress (number of completed entries).
total : int
Task size (total number of entries to create).
done_str : :obj:`str`, optional
Once complete, this string contains the
time it took to assemble the kernel (seconds).
j_end : int
Only generate the columns up to 'j_end'. This creates a
M*3N x j_end*3N kernel matrix, instead of M*3N x M*3N.
Returns
-------
:obj:`numpy.ndarray`
Force field kernel matrix.
