type(dbcsr_data_obj), public :: data_area

holds actual values.

integer, public, DIMENSION(:), POINTER, CONTIGUOUS :: row_i => Null()

the row index of all of the blocks.

integer, public, DIMENSION(:), POINTER, CONTIGUOUS :: col_i => Null()

the column index of all of the blocks.

integer, public, DIMENSION(:), POINTER, CONTIGUOUS :: blk_p => Null()

the pointer into the data array of this block.

integer, public :: lastblk = -1

index of the last block entered into the row_i, col_i, and blk_p data structures

integer, public :: datasize = -1

the actual size of data present in the data element

integer, public :: datasize_after_filtering = -1

tree used to index data blocks (alternative to the row_i, col_i, and blk_p indices when index is scattered).

type(dbcsr_mutable_obj), public :: mutable

the final bcsr matrix
