The problem I run into while doing that is that "copy_dbcsr_to_fm" uses a cp_dbcsr_obj not a dbcsr_obj which I used to create my matrix, is there a way around this?<br><br>-Adam<br><br>On Wednesday, August 1, 2012 2:46:29 AM UTC-6, jgh wrote:<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;">Hi
<br>
<br>have a look into " copy_dbcsr_to_fm ", fm = full matrix.
<br>
<br>Most of the complexity is from the distributed memory of both
<br>types.
<br>Using the fm type (see cp_fm_type.F) is rather easy.

<br>Subject: [CP2K:3953] Quick DBCSR matrix question
<br>
<br>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:
<br>
<br>Real(8) :: BO(1000,1000)
<br>...
<br>DO j=1, dbcsr_nblkcols_total(matrix_a)
<br> DO i=1, dbcsr_nblkrows_total(matrix_a)
<br> dbcsr_function(matrix_a, i, j, data)
<br> BO(i,j)=data
<br> ENDDO
<br>ENDDO
