R-R分布函数的源码，用来测试颗粒物浓度时亲测可用，值得下载(The source of R-R distribution function is used to test particulate matter concentration, so it can be downloaded, and is worth downloading.)

说明：  通过2SeaColor模型，对遥感影像进行水质参数反演(Through the 2seacolor model, the water quality parameters of remote sensing images are inversed)

功能为求解系数矩阵为三对角矩阵或者循环三对角矩阵的线性方程。 输入的四个参数均为行向量，分别对应系数矩阵的上副对角线，主对角线，下副对角线，以及方程等号另一侧的常数矩阵(The four parameters of the input are line vectors, which correspond to the upper diagonal lines of the coefficient matrix, the main diagonal line, the lower diagonal line, and the constant matrix on the other side of the equation.)

说明：  超短脉冲是谐振腔中增益与损耗达到平衡、色散与非线性达到平衡时所产生的。啁啾型脉冲在光纤中传播，因色散作用及各种非线性作用谱线被展宽。(Ultra-short pulses are generated when the gain and loss of the cavity are balanced, and the dispersion and nonlinearity are balanced. Chirped pulses propagate in optical fibers, and their spectral lines are broadened due to dispersion and various non-linear effects.)
