<h4 class="subsection">8.4.9 Exchanging rows and columns</h4>

<p>The following functions can be used to exchange the rows and columns of
a matrix.
</p>
<dl>
<dt><a name="index-gsl_005fmatrix_005fswap_005frows"></a>Function: <em>int</em> <strong>gsl_matrix_swap_rows</strong> <em>(gsl_matrix * <var>m</var>, size_t <var>i</var>, size_t <var>j</var>)</em></dt>
<dd><p>This function exchanges the <var>i</var>-th and <var>j</var>-th rows of the matrix
<var>m</var> in-place.
</p></dd></dl>

<dl>
<dt><a name="index-gsl_005fmatrix_005fswap_005fcolumns"></a>Function: <em>int</em> <strong>gsl_matrix_swap_columns</strong> <em>(gsl_matrix * <var>m</var>, size_t <var>i</var>, size_t <var>j</var>)</em></dt>
<dd><p>This function exchanges the <var>i</var>-th and <var>j</var>-th columns of the
matrix <var>m</var> in-place.
</p></dd></dl>

<dl>
<dt><a name="index-gsl_005fmatrix_005fswap_005frowcol"></a>Function: <em>int</em> <strong>gsl_matrix_swap_rowcol</strong> <em>(gsl_matrix * <var>m</var>, size_t <var>i</var>, size_t <var>j</var>)</em></dt>
<dd><p>This function exchanges the <var>i</var>-th row and <var>j</var>-th column of the
matrix <var>m</var> in-place.  The matrix must be square for this operation to
be possible.
</p></dd></dl>

<dl>
<dt><a name="index-gsl_005fmatrix_005ftranspose_005fmemcpy"></a>Function: <em>int</em> <strong>gsl_matrix_transpose_memcpy</strong> <em>(gsl_matrix * <var>dest</var>, const gsl_matrix * <var>src</var>)</em></dt>
<dd><p>This function makes the matrix <var>dest</var> the transpose of the matrix
<var>src</var> by copying the elements of <var>src</var> into <var>dest</var>.  This
function works for all matrices provided that the dimensions of the matrix
<var>dest</var> match the transposed dimensions of the matrix <var>src</var>.
</p></dd></dl>

<dl>
<dt><a name="index-gsl_005fmatrix_005ftranspose"></a>Function: <em>int</em> <strong>gsl_matrix_transpose</strong> <em>(gsl_matrix * <var>m</var>)</em></dt>
<dd><p>This function replaces the matrix <var>m</var> by its transpose by copying
the elements of the matrix in-place.  The matrix must be square for this
operation to be possible.
</p></dd></dl>
