说明：  基于小波包的带通滤波器设计程序。给出了小波变换的快速算法和重构算法，讨论了应用小波变换进行信号带通滤波的方法，并通过正交小波包对信号的分解，把频率成分复杂的信号分解到各个频带上，根据需要提取指定频率的信号，然后用小波包重构算法对信号进行重构，实现对信号的提取。(Based on wavelet packet band-pass filter design program. Given the fast algorithm of wavelet transform and reconstruction algorithms are discussed using wavelet transform signal band-pass filtering method, and through the wavelet packet to signals can be decomposed, 把 frequency components of complex signal is decomposed into various frequency bands 上, according to need to extract the specified frequency signal, and then reconstructs the signal reconstruction algorithm to achieve the extraction of the signal.)

以上是matlab语言环境中的最小二乘法程序(These are the matlab language environment in the least squares procedure)

说明：  使用蛙跳算法来解决一个工厂流程问题的事例(Frog hopping algorithm solves factory process problems)

This is a simple, yet useful Bloch equation simulator that runs in Matlab. It is written as a MEX function so that it can run reasonably quickly, and simulate RF and a 1D gradient waveform. Simulations can be run for a range of spatial offsets and frequency offsets.
