实现无线电导航的原理，基于三边测量定位对导航和GPS（全球定位系统）的实现。同时实现了，GPS广播星历参数算法，电离层误差、对流层误差、卫星等仿真(Implement the principle of radio navigation, positioning for navigation based on trilateration and GPS (Global Positioning System) implementation. While achieving, GPS broadcast ephemeris parameter algorithm, the ionosphere error, troposphere error, satellite and other simulation)

Find roots of a polynomial with very high degree and multiplicity by this compact routine.

The latest Matlab releases (starting with R2007a) include support for multiple cores. However, Matlab will only take advantage of multiple cores in evaluating certain computations like an FFT or a FIR filtering operation. Matlab will never be able to determine if, for example, consecutive function calls in a for-loop are independent of each other.
