代码说明:

  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. )

    说明:  lms滤波,可以用于去噪。在标准sin的信号基础上加入高频噪声,均匀白噪声和高斯白噪声,再采用lms滤波,可以得到预期波形(LMS filtering can be used for denoising. The expected waveform can be obtained by adding high frequency noise, uniform white noise and Gaussian white noise on the basis of standard sin signal and using LMS filter.)

  • 熵权法(python)
    说明:  熵权法根据各指标的变异程度,利用信息熵计算出各指标的熵权,再通过熵权对各指标的权重进行修正,从而得出较为客观的指标权重。(According to the variation degree of each index, the entropy weight of each index is calculated by using information entropy, and then the weight of each index is revised by the entropy weight, thus objectively obtaining the weight of each index.)
