工程师用Fortran 编程常用程序，包括最小二乘法、牛顿插值、差分法、常用方程求解等，其中还包括 Mathtics 和Qick basic版本源代码。-Fortran、mathics and QB source codes for science and engineering computation

matlab中，利用偏最小二乘法优选最佳波长，构建模型，拟合方程-PLSR, a dimensionality reduction method, is emerging as the most robust and reliable chemometric method for constructing models and aims at determining predictor combinations with maximum covariance with the response
