Assessment results show that the SVD technique can obviously improve identification accuracy as compared to the PI solution.
结果表明,使用奇异值解法能够明显提高频时域法的识别精度。
In seismic inversion, the inverse matrix is mostly huge singular, the ordinary methods cannot be directly used to solve the equation, and the SVD technique must be used.
在地震波阻抗反演中,其反演矩阵多为接近奇异的大型矩阵,不能用一般方法直接求解,而要用奇异值分解(SVD)方法解方程。
