Description: fastBSpline - 一个快速，轻量级的类，它实现
任意阶非均匀B样条曲线
Matlab的样条函数都很一般。这种通用性来自于
速度的代价。对于大规模的应用，包括模型
其中，模型的某些组件中的术语定义嵌合
样条曲线，如广义相加模型，更快的解决方案是
可取的。
该fastBSpline类实现一个轻量级的一套B样条
功能，包括评估，分化和参数拟合。
艰苦的工作是由C代码完成，因而在高达10倍的加速
评估时，评估样条曲线和高达50倍的加速
样条衍生物。
然而， fastBSplines使用的是直观的，高操纵
面向对象的接口，从而使C级性能
而不杂乱。使用CompileMexFiles以编制所需的
文件。如果MEX文件不可用，评估将：M进行
码，所以你仍然可以使用的代码，如果你不能使用一个编译器为你
平台。-fastBSpline- A fast, lightweight class that implements
non-uniform B splines of any order
Matlab s spline functions are very general. This generality comes at
the price of speed. For large-scale applications, including model
fitting where some components of the model are defined in terms of
splines, such as generalized additive models, a faster solution is
desirable.
The fastBSpline class implements a lightweight set of B-spline
features, including evaluation, differentiation, and parameter fitting.
The hard work is done by C code, resulting in up to 10x acceleration
for evaluating splines and up to 50x acceleration when evaluating
of spline derivatives.
Nevertheless, fastBSplines are manipulated using an intuitive, high-
level object-oriented interface, thus allowing C-level performance
without the messiness. Use CompileMexFiles to compile the required
files. If mex files are not available, evaluation will be done in .m
