title: Clarification of the leading dimension in CUBLAS when transposing
body: <p>For a matrix <code>A</code>, the <a href="http://docs.nvidia.com/cuda/cublas/index.html#topic_9_1">documentation</a> only states that the corresponding leading dimension parameter <code>lda</code> refers to the:</p>
  
  <blockquote>
    <p>leading dimension of two-dimensional array used to store the matrix A</p>
  </blockquote>
  
  <p>Thus I presume this is just the number of rows of <code>A</code> given CUBLAS' column major storage format. <strong>However, when we consider <code>Op(A)</code>, what does the leading dimension refer to now?</strong></p>
