tf.searchsorted

Searches input tensor for values on the innermost dimension.

A 2-D example:

sorted_sequence = [[0, 3, 9, 9, 10],
                   [1, 2, 3, 4, 5]]
values = [[2, 4, 9],
          [0, 2, 6]]

result = searchsorted(sorted_sequence, values, side="left")

result == [[1, 2, 2],
           [0, 1, 5]]

result = searchsorted(sorted_sequence, values, side="right")

result == [[1, 2, 4],
           [0, 2, 5]]
Args
sorted_sequence N-D Tensor containing a sorted sequence.
values N-D Tensor containing the search values.
side 'left' or 'right'; 'left' corresponds to lower_bound and 'right' to upper_bound.
out_type The output type (int32 or int64). Default is tf.int32.
name Optional name for the operation.
Returns
An N-D Tensor the size of values containing the result of applying either lower_bound or upper_bound (depending on side) to each value. The result is not a global index to the entire Tensor, but the index in the last dimension.
Raises
ValueError If the last dimension of sorted_sequence >= 2^31-1 elements. If the total size of values exceeds 2^31 - 1 elements. If the first N-1 dimensions of the two tensors don't match.
