matlab code for sweep generation

利用MATLAB实现空间直角坐标系与大地坐标系转换(MATLAB space rectangular geodetic coordinate system conversion)

近似熵是一种衡量衡量非线性时间序列复杂性的非线性动力学分析方法，其物理意义 为熵值越大，时间序列的自我相似性越低，序 列越复杂，反之序列自我相似性越高；并且样 本熵对于序列长度依赖弱，仅需较短的数据就 能够得到稳健的熵值，同时其计算不需对数据 粗粒化，具有较好的抗干扰能力 (Approximate entropy is a measure to measure the complex nonlinear dynamics of nonlinear time series analysis method, the physical meaning of entropy value is larger, the lower the self-similarity of the time series, the more complex the sequence, whereas sequence of self-similarity the higher and the sample entropy weak dependence for the length of the sequence, only shorter data can be healthy entropy value, calculated without data coarse-grained, with good anti-jamming capability)

自己编写的matlab简单计算，用于计算矩阵的加减乘与求逆，特征行列式等(I have written matlab simple calculation used to calculate the matrix addition and subtraction, multiplication and inversion, characteristic determinant, etc.)

推算表,还没有写完,下面没有了思路了,我会继续写完他的.(Projection table, has not yet finished, the following no idea, and I will continue to finish him.)
