系统下,地球坐标转换的源代码,在WGS-84坐标和北京54坐标之间的一套转换参数,可以全国通用的，在每个地方会不一样，因为它们是两个不同的椭球基准。 // WGS2GK.CPP : C++ version of Ottmar Labonde s WGSDHDN3.PAS with CPU time measurement // compile with MS Visual C++ version 6.0 or do the necessary modifications ...

This a Bayesian ICA algorithm for the linear instantaneous mixing model with additive Gaussian noise [1]. The inference problem is solved by ML-II, i.e. the sources are found by integration over the source posterior and the noise covariance and mixing matrix are found by maximization of the marginal ...

在linux环境下，开发的一个类似ping的程序，计算round trip time，即往返时间，可选择使用TCP或UDP

This code can be used to model a microstrip line or a microstrip patch antenna (the particular problem being modeled is determined at compile-time via various declarations).

PID calculations for the _pid structure *a. This function uses the positional form of the pid equation, and incorporates an integral windup prevention algorithim. Rectangular integration is used, so this function must be repeated on a consistent time basis for accurate control.
