espnet2.enh.layers.beamformer.tik_reg(mat, reg: float = 1e-08, eps: float = 1e-08)

Perform Tikhonov regularization (only modifying real part).

• Parameters:
  • mat (torch.complex64/ComplexTensor) – input matrix (…, C, C)
  • reg (float) – regularization factor
  • eps (float)
• Returns: regularized matrix (…, C, C)
• Return type: ret (torch.complex64/ComplexTensor)
