Functions

compute_tikhonov_modified_singular_values(...)	Computes the modified singular values that would be seen in Tikhonov regularization.
frf_inverse(frf_matrix[, method, ...])	Computes the inverse of an FRF matrix for source estimation problems.
pinv_by_tikhonov(frf_matrix[, ...])	Computes the pseudo-inverse of an FRF matrix via Tikhonov regularization
pinv_by_truncation(frf_matrix, ...)	Computes the pseudo-inverse of an FRF matrix where a fixed number of singular values are retained for the inverse
