19 Jan 2011 B-spline tools Basic toolbox for polynomial B-splines on a uniform grid. OO overloading of common operators. Author: Jan Tore Korneliussen

First of all, thanks a lot for the code..In bsplineNdtrans.m, roots of pole are being calculated and poles only between _1 to +1 are being considered. The roots of pole for any particular spline will be same and i feel this as a redundant calculation.
Also i am interested in calculating the partial derivatives(2-D data) i.e wrt x,y,xx,yy,xy,etc. It would be of great help if you can illustrate these calculations with the help of an example
Any help would be greatly appreciated..
