-- Function File: POLYLINE = curve2polyline (CURVE)
-- Function File: POLYLINE = curve2polyline (...,PROPERTY,VALUE,...)
Adaptive sampling of a parametric curve.
The CURVE is described as a 2-by-N matrix. Rows correspond to the
polynomial (compatible with 'polyval') describing the respective
component of the curve. The curve must be parametrized in the
interval [0,1]. The vertices of the polyline are accumulated in
regions of the curve where the curvature is higher.
*Parameters*
''Nmax''
Maximum number of vertices. Not used.
''Tol''
Tolerance for the error criteria. Default value '1e-4'.
''MaxIter''
Maximum number of iterations. Default value '10'.
''Method''
Not implemented.

-- Function File: POLYGON = shape2polygon (SHAPE)
-- Function File: POLYGON = shape2polygon (...,PROPERTY,VALUE,...)
Transforms a 2D shape described by piecewise smooth polynomials
into a polygon.
SHAPE is a n-by-1 cell where each element is a pair of polynomials
compatible with polyval. POLYGON is a k-by-2 matrix, where each
row represents a vertex. The property-value pairs are passed to
'curve2polyline'.

-- Function File: A = shapearea (PP)
Calculate the area of a 2D shape defined with piecewise smooth
polynomials.
Shape is defined with piecewise smooth polynomials. PP is a cell
where each elements is a 2-by-(poly_degree+1) array containing a
pair of polynomials.
'px(i,:) = pp{i}(1,:)' and 'py(i,:) = pp{i}(2,:)'.

-- Function File: CM = shapecentroid (PP)
Centroid of a simple plane shape defined with piecewise smooth
polynomials.
The shape is defined with piecewise smooth polynomials. PP is a
cell where each elements is a 2-by-(poly_degree+1) matrix
containing a pair of polynomials. 'px(i,:) = pp{i}(1,:)' and
'py(i,:) = pp{i}(2,:)'.
The edges of the shape should not self-intersect. This function
does not check for the sanity of the shape.
