Frequency Domain Method to calculate the Difference of Arrival of Sound.

netcdf插件安装和.nc格式数据的读取,主要操作mexcdf53.dll和netcdf.dll文件,适于从事海洋和大气专业的的数据格式.作者在实际中用matlab处理了一些此类数据，简单说来就是安装一个插件即可.现将我们的方法具体地写出，以供参考(NetCDF installation and plug-ins. nc format to read data, the main operating mexcdf53.dll and netcdf.dll document, suitable for marine and atmospheric data format professional. Author matlab used in the actual treatment a number of such data, simple to say that you can install a plug-in. The way we write specifically for reference)
