Convert WGS 84 (CTS, ECEF) Coordinates to ECI (CIS, Epoch J2000.0) Coordinates. This function has been vectorized for speed. The associated error in converting between coordinate frames is on the order of 1.2*10^-11 km when compared to STK ephemeris

空间三维最优化三级运载火箭弹道求解算法。基于Matlab和GPOPS 5.2工具箱。实测收敛快，但对初值较敏感，轨道大于800km时需仔细调整参数。附带GPOPS 5.2工具箱和程序说明，可与STK接口。-Three dimensional space rocket trajectory optimization algorithm. Based on Matlab and GPOPS 5.2 toolbox. Found fast convergence, but more sensitive
