  <DESCRIPTION>
    <P>
    Considering a surface given through a list <VERB>seclist</VERB> of sections in the 
    <VERB>(x,z)</VERB> plane  <VERB>[m [,x]]=secto3d(seclist [,npas])</VERB> returns a matrix <VERB>m</VERB>
    which contains a regular discretization of the surface.

        <SP>The i-th row of the matrix m corresponds to the i-th section</SP>

    <P>
    Each section <VERB>seclist(i)</VERB> is described by a (2,.) matrix which gives respectively the x 
    and z coordinates of points.</P>
    <P><VERB>[m]=secto3d(seclist ,x)</VERB> : in that case the x-vector gives the discretization 
    of the x-axis for all the sections</P>
