<p class="MsoNormal"><span style="font-size:11.0pt;color:black">I am simply interested in obtaining a vector with x_i = \sum_j | A_{i, j} | for each row “i” in the matrix A. I found MatGetColumnNorms(), but no row version. I am wondering if it is more efficient
to calculate the transpose A^T and then MatGetColumnNorms() or maybe iterate through each row with MatGetRow() and calculate \sum_j | A_{i, j} | by hand by myself.</span><span style="color:black"><o:p></o:p></span></p>
