说明：  最小二乘法拟合曲线的一个小程序，采用C++程序，(Least-squares fitting curve C++ program)

这是用于求解精确求解zoeppritz方程的程序，可用于AVO反演，合成地震记录等(This function computes the particle displacement reflection and transmission coefficients (the relative displacement amplitudes) for a solid-solid interface, a liquid-solid interface, a solid-liquid interface, and a liquid-liquid interface. The medium on each side of a given interface is perfectly elastic. The output is the value of the reflection or transmission coefficient, specified by the user at the incidence angle anginc (see input parameters). )
