These correspond in the following way to the BLAS symbols:<br>:trans <code>= CblasTrans</code><br>:notrans = <code>CblasNoTrans</code><br>:conjtrans =<code></code><code></code> <code>CblasConjTrans</code>.  <br>That is, transpose, no transpose, conjugate transpose.  Look at the BLAS documentation for more information; unfortunately, the GSL BLAS documentation like <a href="http://www.gnu.org/s/gsl/manual/html_node/Level-2-GSL-BLAS-Interface.html">http://www.gnu.org/s/gsl/manual/html_node/Level-2-GSL-BLAS-Interface.html</a> doesn&#39;t really explain this much.  In other words, the GSLL documentation is weak, just like the GSL documentation is :-)  If you just want a regular product, use :notrans (no transpose of the matrix before multiplying), which is the default.<br>

Hello all,<br>
    I&#39;m unable to find out how to use the :trans, :notrans, and :conjtrans keywords when using the matrix-product function. Could someone help me out with this?<br>
<br>
Thanks<br>
