this file is matlab code for hunting search algorithm.i think it can be so useful.thanks

GMSK信号调制和解调的仿真代码，包含一比特差分、2比特差分、鉴频等常用GMSK解调方案.之前上传的GMSK Modem差分相干、2比特差分解调存在问题。(GMSK demodulation schemes including one bit differential decoding, two bit differential decoding, differential coherent and digital frequency discriminating methods.)

分析传统双向渐进结构优化方法（Bi-directional evolutionary structural optimization，简称BESO）存在不足的基础上，针对性的对数值计算进行了合理的改进。并在此基础上分别对宏观结构、微结构优化、材料/结构一体化等相关问题进行了多尺度、多相复合材料布局及拓扑优化等层次系统地研究(Based on the analysis of the shortcomings of the traditional Bi-directional evolutionary structural optimization (BESO), a reasonable improvement is made for numerical computation. Based on that, multi-level, multi-phase composite material layout and topology optimization are studied systematically.)

基于麦克风阵列的声源定位方法很多，相位变换加权的可控响应功率SRP-PHAT声源定位算法在混响环境中有较强的鲁棒性，可实现真实环境中的声源定位，因此该算法得到了广泛应用。SRP-PHAT对阵型没有特定要求，因此也适用于分布式阵列，事实上很多基于分布式阵列的定位系统采用了该算法。(This function creates an acoustic image from a set of microphone array signals using a steered response power (SRP algorithm).This particular version uses only integer shifts on the input signals for the delay and sum operation, and computes the coherent average power (rather than total average power), which does not include the power terms for each individual microphone signal. So the coherent power is effectively the cross-correlation between different microphone signals without the self power terms, and can therefore be negative.)

It is a matlab code used to calculate the subspace algorithm of signals.
