Spline Toolbox

bspline

Display a B-spline and its polynomial pieces

Syntax

• bspline(t)
  bspline(t,window)
  pp = bspline(t)
  

Description

bspline(t) plots , i.e., the B-spline with knot sequence t, as well as the polynomial pieces of which it is composed.

bspline(t,window) does the plotting in the subplot window specified by window; see the MATLAB command subplot for details.

pp = bspline(t) plots nothing but returns the ppform of the B-spline.

Examples

The statement pp=fn2fm(spmak(t,1),'pp') has the same effect as the statement pp=bspline(t). 

See the demo bsplidem for typical uses of this command.
