  <DESCRIPTION>
    <P>
For a vector  or a matrix x,  [q]=quart(x,y)
returns in the vector q the quartiles of x.

[q]=quart(x,'r')        (or,         equivalently,
[q]=quart(x,1)) are the   rowwise percentiles.  It
returns in  each  column of    the matrix  q   the
quartiles  of   data   in the   corresponding column  of
x.</P>
    <P>
[q]=quart(x,'c')        (or,         equivalently,
[q]=quart(x,2)) are the  columnwise quartiles.  It
returns in each row of  the matrix q the quartiles
of data in the corresponding row of x.</P>
