set_icov

set_icov(self) -> None
Computes and sets the inverse covariance matrix for the P1 power spectrum data and full power spectrum data.
+
+This method processes the main dataset (`data`) and any additional dataset (`extra_data`) associated
+with the object. For each dataset:
+- It computes the inverse covariance matrices for the power spectrum (`Pk_kms`) at different redshifts,
+  incorporating an emulator error factor.
+- It computes the inverse covariance matrix for the full power spectrum data, if available.
+
+The resulting inverse covariance matrices are stored in instance attributes.
+
+Attributes Modified:
+--------------------
+icov_Pk_kms : list of numpy.ndarray
+    List of inverse covariance matrices for the power spectrum of the main dataset at different redshifts.
+
+full_icov_Pk_kms : numpy.ndarray or None
+    Inverse covariance matrix for the full power spectrum of the main dataset.

+    Inverse covariance matrix for the full power spectrum of the additional dataset.
+    Set to `None` if the full power spectrum is not available or if `extra_data` is not provided.
+
+Notes:
+-----
+- The emulator error is added to the diagonal of the covariance matrix before inverting. The error is
+  computed as `(data.Pk_kms * emu_cov_factor) ** 2`, where `emu_cov_factor` is an attribute of the object.
+- The method iterates over redshift bins (`data.z`) and processes the covariance matrices accordingly.
+- If the dataset (`data` or `extra_data`) is `None`, no processing occurs for that dataset.

+Raises:
+-------
+ValueError:
+    If the covariance matrix inversion fails (e.g., due to singularity).
