说明：  声学基础 -南大版课后习题答案，清晰版本，89页版本(Fundamentals of Acoustics - answer to exercises in Nantah)

采用CG法求解稀疏对称奇异矩阵得到的Ax=b(Implementation of a conjugate-gradient type method for solving sparse linear equations: Solve Ax = b or (A- sI)x = b. The matrix A- sI must be symmetric but it may be definite or indefinite or singular. The scalar s is a shifting parameter – it may be any number. The method is based on Lanczos tridiagonalization. You may provide a preconditioner, but it must be positive definite. )
