短时傅里叶，matlab程序，经过检验可以正常使用，(stft short-time ft)

利用MALAB实现的关于变压器差流计算的问题，对差流的提取很有意义。(MALAB achieve on transformer differential current calculated differential current extraction makes sense.)

基于均匀线阵，利用四阶累积量产生虚拟阵元，可估计出比真实阵元数更多的信号源，已达到DOA估计的目的，且具有较好的分辨率。(Based on uniform linear array, using fourth-order cumulants to generate the virtual array element can be estimated more than the true number of array element signal source, the purpose has been to DOA estimation, and has good resolution.)

说明：  设计滤波器：设定10个零点，计算出多项式系数，作为滤波器系数； 取出绝对值较大的一半零点，重新设计滤波器；用剩下的绝对值较小的一半零点，重新设计滤波器。(Design a filter: Set of 10 zeros, calculate the polynomial coefficients as filter coefficients remove the larger half of the absolute value of zero, re-design filter with the remaining half of the smaller absolute zero, re-design filter.)

这是一个小波变换的程序，滤去噪声实现语音增强(This is a wavelet transform procedures, filter out the noise to realize speech enhancement)

说明：  TSP问题,即旅行商问题,matlab环境下可以运行(TSP problem, that is, traveling salesman problem, matlab environment can run)

给定离散地震动加速度数据a、反应谱控制周期点tp、离散时间间隔dt、阻尼比z，计算地震动加速度反应谱rspa以及最大反应值出现的时刻tMax。(Given the discrete ground-motion acceleration data a, the response spectral controlling period tp, the discrete time distance dt, and the damping ratio z, calculate the ground-motion acceleration response spectrum rspa and the time loction of the occurrence of maximum response.)
