[CP2K:3953] Quick DBCSR matrix question

[hut... at pci.uzh.ch]

Hi

have a look into " copy_dbcsr_to_fm ", fm = full matrix.

Most of the complexity is from the distributed memory of both
types.
Using the fm type (see cp_fm_type.F) is rather easy.

Is there an easy way to retrieve matrix data by row and column? So I could do something like this to store values in an array:

Real(8) :: BO(1000,1000)
...
DO j=1, dbcsr_nblkcols_total(matrix_a)
    DO i=1, dbcsr_nblkrows_total(matrix_a)
         dbcsr_function(matrix_a, i, j, data)
         BO(i,j)=data
    ENDDO
ENDDO
