<br>
<br>unfortunately DBCSR's API is not yet fully documented.
<br>However, you should have a look at the file dbcsr_example_3.F .
<br>
<br>We are also currently in the process of separating DBCSR from CP2K.
<br>As a fist step we launched a website where you can download DBCSR as a 
<br>standalone tarball: <a href="http://dbcsr.cp2k.org/" target="_blank" onmousedown="this.href='http://www.google.com/url?q\75http%3A%2F%2Fdbcsr.cp2k.org%2F\46sa\75D\46sntz\0751\46usg\75AFQjCNFugSzsOJAi15UFZEHPm3T93mdUDA';return true;" onclick="this.href='http://www.google.com/url?q\75http%3A%2F%2Fdbcsr.cp2k.org%2F\46sa\75D\46sntz\0751\46usg\75AFQjCNFugSzsOJAi15UFZEHPm3T93mdUDA';return true;">http://dbcsr.cp2k.org/</a>
<br>
<br>Out of curiosity, may I ask for which project you are planing to use 
<br>DBCSR?
