BLDC Motor Modelling and Control – A Matlab® /Simulink® Implementation

针对目前流行的一种文件格式segy 处理的软件包，( Since the original SEG Y Data Exchange Format [revision 0, reference page 45] was published in 1975 it has achieved widespread usage within the geophysical industry. This widespread usage has brought about many proprietary variations. Since the publication of SEG Y rev 0, the nature of seismic data acquisition, processing and seismic hardware has changed significantly. The introduction of 3-D acquisition techniques and high speed, high capacity recording media dictate the need for revisions to the SEG Y rev 0 format. The major changes introduced by SEG Y rev 1 are: standardizing the location of header information needed for current processing practices and defining a SEG Y data set as a byte stream format. The SEG Technical Standards Committee strongly encourages producers and users of SEG Y data sets to move to the revised standard in an expeditious fashion. )

说明：  医学成像技术滤波反投影 内含R-L， R-S sweit滤波 重建后图像清晰，效果相当好(medical imaging technology filter-projection includes R-L, R-S sweit filtering reconstruction after the pictures are clear, the results are pretty good)
