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
