  <SHORT_DESCRIPTION name="mtlb_rcond">Matlab rcond emulation function</SHORT_DESCRIPTION>

  <DESCRIPTION>

    <P>Matlab and Scilab <VERB>rcond</VERB> behave differently in some particular cases:</P>

    <DESCRIPTION_INDENT>
    <DESCRIPTION_ITEM>
    <ITEMIZE>
      <ITEM>
        <SP>
        With empty matrix: Matlab <VERB>rcond</VERB> returns <VERB>Inf</VERB> and
	Scilab <VERB>rcond</VERB> returns <VERB>[]</VERB>
        </SP>
      </ITEM>
    </ITEMIZE>
    </DESCRIPTION_ITEM>
    </DESCRIPTION_INDENT>

    <P>
    The function <VERB>mtlb_rcond(A)</VERB> is used by
    <VERB>mfile2sci</VERB> to replace <VERB>rcond(A)</VERB> when it was not
    possible to know what was the input while porting Matlab code to Scilab. This function will
    determine the correct semantic at run time. If you want to have a
    more efficient code it is possible to replace <VERB>mtlb_rcond</VERB> calls:
    </P>

    <DESCRIPTION_INDENT>
    <DESCRIPTION_ITEM>
    <ITEMIZE>
      <ITEM>
        <SP>
        If <VERB>A</VERB> is not an empty matrix,
        <VERB>mtlb_rcond(A)</VERB> may be replaced by <VERB>rcond(A)</VERB>
        </SP>
      </ITEM>
    </ITEMIZE>
    </DESCRIPTION_ITEM>
    </DESCRIPTION_INDENT>

    <P>Caution: <VERB>mtlb_rcond</VERB> has not to be used for hand coded functions.</P>
