LabVIEW implementation of neural net with 2 layers. Back Error Propagation learning example.

GMP是计算任意精度的数学库, 包括支持整数,有理数和浮点. GMP包括大量的接口函数.-GMP is a free library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers. There is no practical limit to the precision except the ones implied by the available memory in the machine GMP runs on. GMP has a rich set of functions, and the functions have a regular interface.

FFT是离散傅立叶变换的快速算法，可以将一个信号变换到频域。有些信号在时域上是很难看出什么特征的，但是如 果变换到频域之后，就很容易看出特征了。这就是很多信号 分析采用FFT变换的原因。另外，FFT可以将一个信号的频谱 提取出来，这在频谱分析方面也是经常用的。虽然很多人都知道FFT是什么，可以用来做什么，怎么去 做，但是却不知道FFT之后的结果是什意思、如何决定要使用 多少点来做FFT。具体的频率细分法可参考相关文献。
