e3x.ops.indexed.dense_pairwise_indices

e3x.ops.indexed.dense_pairwise_indices(num, mask_self=True)[source]

Generates a dense index list for all pairs of num elements.

Parameters:

num (int) – Number of elements.
mask_self (bool, default: True) – Whether self-connections (loops) should be masked out.

Return type:

Union[Integer[Array, '... num num-1'], Integer[Array, '... num num']]

Returns:

A dense index list specifying all pairs.
