This function is the inverse of upper function: it computes symmetric matrices from their weighted upper triangular parts.

Parameters

Tndarray, shape (…, n_channels * (n_channels + 1) / 2): Weighted upper triangular parts of symmetric matrices.

Returns

Xndarray, shape (…, n_channels, n_channels): Symmetric matrices.
