C 语言实现线性插值，直接与三角形2中，包括矩阵运算的H 文件-C language realization of the linear interpolation directly with triangle 2, including the file of the H matrix operations

通过对点在坐标系中的确定，可以对点进行线性插值，抛物线插值，拉格朗日插值。-The determination of the point in the coordinate system can be linear interpolation, to point parabolic interpolation, Lagrange interpolation.

用于GIS行业的空间插值算法，经过本人调试，可以运行。-Used for spatial interpolation algorithm of GIS industry, after debugging, you can run.
