短时傅里叶变换 时频分析 matlab 信号处理 轴承故障 故障信号

This code computes the distance and azimuth an earthquake to a station. It is necessary to provide the latitude and longitude bothe for the earthquake and the station.

部分激光经过外腔反馈回激光器，产生扰动，并调节反馈光能量 实现混沌光输出(Part of the external cavity laser is fed back through the laser, produces disturbances, feedback and adjust the light output of the light energy of Chaos)

说明：  基于matlab GUI的数字滤波器源程序(The digital filter based on source code matlab GUI)

This is a matlab program using the most liklihood method to estimate the SNR of a sinusoid wave. The experiment shows that it works well at normal SNR, while the noise is Gausian.

说明：  批量把日数据转成月平均和季平均数据，需要把原始数据整理成excel(To convert daily data into monthly and seasonal data in batches, we need to organize the original data into excel.)

说明：  基于超低功耗微型心电听诊仪的设计.pdf(2006MAY19 ME DSP TS1.pdf)

独立成分分析程序，实现独立成分分析的函数，可以再matlab中直接调用(Independent component analysis, independent component analysis functions directly call can matlab)

修改过的比较实用易于理解的gabor滤波，附有主函数调用部分，便于使用(Modified more practical easy to understand gabor filtering, with the main part of the function call, easy to use)

It is about matlab which depicts brain image segmentation
