CeedElemRestriction¶
-
int CeedPermutePadOffsets(const CeedInt *offsets, CeedInt *blk_offsets, CeedInt num_blk, CeedInt num_elem, CeedInt blk_size, CeedInt elem_size)¶
Permute and pad offsets for a blocked restriction.
Utility Functions
- Parameters
offsets – [in] Array of shape [num_elem, elem_size]. Row i holds the ordered list of the offsets (into the input CeedVector) for the unknowns corresponding to element i, where 0 <= i < num_elem. All offsets must be in the range [0, l_size - 1].
blk_offsets – [out] Array of permuted and padded offsets of shape [num_blk, elem_size, blk_size].
num_blk – [in] Number of blocks
num_elem – [in] Number of elements
blk_size – [in] Number of elements in a block
elem_size – [in] Size of each element
- Returns
An error code: 0 - success, otherwise - failure
