滤波、解方程、模拟测井曲线、扸及、测井曲线拉伸机压缩复式变换等各种算法-The array dimensions are numbered, which makes it easy to add

　　　　　　functions for arrays of higher dimensions.　In particular,

　　　　　　the 1st dimension of length n1 is always the fastest dimension,

　　　　　　the 2nd dimension of length n2 is the next fastest dimension,

　　　　　　and so on.　Note that the 1st (fastest) dimension n1 is the

　　　　　　first argument to the allocation functions defined below, but

　　　　　　that the 1st dimension is the last subscr ipt in a[i2][i1].

　　　　　　(This is another important difference between C and Fortran.)
