Detailed Description

keeps the information about the structure of a full matrix

Parameters

para_env	the parallel environment of the matrices with this structure
context	the blacs context (parallel environment for scalapack), should be compatible with para_env
descriptor	the scalapack descriptor of the matrices, when using scalapack (ncol_block=descriptor(6), ncol_global=descriptor(4), nrow_block=descriptor(5), nrow_global=descriptor(3))
ncol_block	number of columns of a scalapack block
nrow_block	number of rows of a scalapack block
nrow_global	number of rows of the matrix
ncol_global	number of rows
first_p_pos	position of the first processor (for scalapack)
row_indices	real (global) indices of the rows (defined only for the local rows really used)
col_indices	real (global) indices of the cols (defined only for the local cols really used)
nrow_locals	nrow_locals(i) number of local rows of the matrix really used on the processors with contextmepos(1)==i
ncol_locals	ncol_locals(i) number of local rows of the matrix really used on the processors with contextmepos(2)==i
ref_count	reference count (see doc/ReferenceCounting.html)
local_leading_dimension	leading dimension of the data that is stored on this processor

readonly attributes:

Parameters

nrow_local	number of local rows really used on the actual processor
ncol_local	number of local cols really used on the actual processor

Note

use cp_fm_struct_get to extract information from this structure
