Inverse upper function.

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.
