nf3d Rectangular facets to plot3d parameters

## Syntax

    [xx,yy,zz]=nf3d(x,y,z)

## Arguments

x,y,x,xx,yy,zz

  6 real matrices

## Description

Utility function. Used for transforming rectangular facets coded in three matrices x,y,z to scilab code for facets accepted by plot3d.

## Examples

    //A sphere...
    u = linspace(-%pi/2,%pi/2,40);
    v = linspace(0,2*%pi,20);
    x= cos(u)'*cos(v);
    y= cos(u)'*sin(v);
    z= sin(u)'*ones(v);
    //plot3d2(x,y,z) is equivalent to...
    [xx,yy,zz]=nf3d(x,y,z); plot3d(xx,yy,zz)
