Scatter

scatter(values, index[, out_size, aggr, axis])	Default function for performing all scattering operations.
scatter_add(src, index, values)	Scatters values at index within src.
scatter_max(src, index, values)	Scatters values at index within src.
scatter_mean(values, index, out_size[, axis])	Computes the mean of values that are scattered along a specified axis, grouped by index.
scatter_softmax(values, index, out_size[, axis])	Computes the softmax of values that are scattered along a specified axis, grouped by index.
degree(index[, num_nodes, edge_weights])	Counts the number of ocurrences of each node in the given index.
invert_sqrt_degree(degree)	Computes the inverted square root of the degree array.
