espnet2.enh.layers.wpe.get_filter_matrix_conj(correlation_matrix: Tensor | ComplexTensor, correlation_vector: Tensor | ComplexTensor, eps: float = 1e-10) → Tensor | ComplexTensor

Calculate (conjugate) filter matrix based on correlations for one freq.

• Parameters:
  • correlation_matrix – Correlation matrix (F, taps * C, taps * C)
  • correlation_vector – Correlation vector (F, taps, C, C)
  • eps
• Returns: (F, taps, C, C)
• Return type: filter_matrix_conj (torch.complex/ComplexTensor)
