For example, Octave can easily tell you if all the elements of a matrix are finite, or are less than some specified value. Octave can also rotate the elements, extract the upper- or lower-triangular parts, or sort the columns of a matrix. <ul class="menu"> <li><a accesskey="1" href="Finding-Elements-and-Checking-Conditions.html#Finding-Elements-and-Checking-Conditions">Finding Elements and Checking Conditions</a> <li><a accesskey="2" href="Rearranging-Matrices.html#Rearranging-Matrices">Rearranging Matrices</a> <li><a accesskey="3" href="Applying-a-Function-to-an-Array.html#Applying-a-Function-to-an-Array">Applying a Function to an Array</a> <li><a accesskey="4" href="Special-Utility-Matrices.html#Special-Utility-Matrices">Special Utility Matrices</a> <li><a accesskey="5" href="Famous-Matrices.html#Famous-Matrices">Famous Matrices</a> </ul> </body></html>
