fft_2d_test

这个程序可以用来在matlab环境下读入和写出.ini文件的内容，因为matlab并没有提供专门读写.ini的函数，所以这个函数很实用(This procedure can be used to read into matlab environment and to write. Ini file, because matlab does not provide specialized reading and writing. Ini function, this function is very useful)

阵列信号处理中，能够识别空间多信号源的方向(Array signal processing, multiple sources to identify the direction of space)

匹配函数：他的功能是实现函数的匹配运算，功能交好(ftghhhhhh)

这是matlab课本的对应的习题解答 用于学习和交流只用 请勿用做非法用途(this is the answer of some question in the book matlab,only for study and communication )

compare with 2 image

说明：  利用盲源分离原理的方法，可以实现多路信号的同时恢复。(The method of blind source separation can realize simultaneous recovery of multiple signals.)

蚁群算法及应用，这本书不错，里面讲得也很详细(Ant colony algorithm and its application, this book is true, which also speaks in great detail)

NVH用7自由度模型，simulink，可重新设定参数(NVH model with seven degrees of freedom, simulink, can be re-set parameters)

二维的TM波打到一个方形的金属柱上，边界条件为PML(TM wave hit a two-dimensional square metal column, PML boundary conditions)

频域波束成形算法，适用于所有一维和二维阵列的波束成形计算。对于采样时间较短的信号，采用了2次分段，对于采样时间足够的信号则只需要1次分段计算。计算结果包含成像图结果和各扫描点处的频谱结果(Frequency domain beamforming algorithm, applicable to all one-dimensional and two-dimensional array beam forming calculations. For shorter sampling signal, using a second segment, the sampling time sufficient signal need only 1 segment calculations. Calculation results include the results of spectral imaging of the results of each scan point)
