Display a B-spline and its polynomial pieces
Syntax
bspline(t) bspline(t,window) pp = bspline(t)
Description
bspline(t) plots B(·|t), i.e., the B-spline with knot sequence t, as well as the polynomial pieces of which it is composed.
If the second argument, window, is present, the plotting is done in the subplot window specified by window; see the MATLAB command subplot for details.
If there is an output argument, then nothing is plotted, and the ppform of the B-spline is returned instead.
Examples
The statementpp=fn2fm(spmak(t,1),'pp') has the same effect as the statement pp=bspline(t).
See the demo bsplidem for typical uses of this M-file.
