ResourceScatterSub

public final class ResourceScatterSub

Subtracts sparse updates from the variable referenced by `resource`.

This operation computes

# Scalar indices ref[indices, ...] -= updates[...]

# Vector indices (for each i) ref[indices[i], ...] -= updates[i, ...]

# High rank indices (for each i, ..., j) ref[indices[i, ..., j], ...] -= updates[i, ..., j, ...]

Duplicate entries are handled correctly: if multiple `indices` reference the same location, their contributions add.

Requires `updates.shape = indices.shape + ref.shape[1:]` or `updates.shape = []`.
