基于Levenberg-Marquardt的曲线/面拟合(C library for Levenberg-Marquardt least-squares minimization and curve fitting)

说明：  reduced mechanism for dodecane which can be used for auto-ignition and combustion calculations. The reduced mechanism can be coupled with any CFD codes like CHEMKIN, Fluent and KIVA.

说明：  fortran 学习软件非常有用啊，请管理员加我。
