NRBDEGELEV: Elevate the degree of the NURBS curve or surface. Calling Sequence: ecrv = nrbdegelev(crv,utimes); esrf = nrbdegelev(srf,{utimes,vtimes}); Parameters: crv : NURBS curve, see nrbmak. srf : NURBS surface, see nrbmak. utimes : Increase the degree along U direction utimes. vtimes : Increase the degree along V direction vtimes. ecrv : new NURBS structure for a curve with degree elevated. esrf : new NURBS structure for a surface with degree elevated. Description: Degree elevates the NURBS curve or surface. This function uses the B-Spline function bspdegelev, which interface to an internal 'C' routine. Examples: Increase the NURBS surface twice along the V direction. esrf = nrbdegelev(srf, 0, 1); See: bspdegelev
