<p>Octave is a weakly typed programming language. Thus it is possible to
call a function with arguments, that probably cause errors or might have
undesirable side effects. For example calling a string processing function
with a huge sparse matrix.
</p>
<p>It is good practice at the head of a function to verify that it has been
called correctly. Octave offers several functions for this purpose.
