regress-137

The following Matlab project contains the source code and Matlab examples used for fitting an ellipse to a given set of points. The most accurate and robust fit minimizes geometric (orthogonal) distances the observed points to the fitting curve.

frost模型进行空时波束合成，增加了阵列的自由度，既可以处理宽带信号也可以进行窄带信号。(When frost empty beam synthesis model, the degree of freedom of the array, can handle both narrow-band signal may be a broadband signal.)

用Matlab处理GPS导航卫星观测数据的程序，也就是O文件，Rinex 2.11版本，代码仅200多行，且包含大量注释，于2017.12.2日调试通过，可顺利读取体积达10M+的O文件，读取的数据准确无误。函数调用格式： [APXYZ DeltaHEN signal_type obsdata] = read_obs(‘krgg3340.17o’)(Using Matlab to process GPS navigation satellite observation data program, that is, O file, Rinex 2.11 version, the code is only more than 200 rows, and contains a lot of annotations. It debugged on 2017.12.2 day. It can smoothly read the O file with volume up to 10M+, and the data read is accurate.)
