"Xsmys"=>"X Squared Minus Y Squared" subtracts the square of vector Y from the square of vector X.

Parameters

x_ptr	x vector input. 24bit integers unpacked.
y_ptr	y vector input. 24bit integers unpacked.
out_ptr	output vector. 24bit integers unpacked, no extra stride, and rounded by rounding_bits. output can overlap either or both inputs.
length	Number of elements in the vectors (data samples). Must be a multiple of 2, at least 4, and no greater than 512. Does not include the stride.
rounding_bits	Number of bits to round the output by. 0 => no rounding, maximum of 31.

Returns

kAxonResultSuccess on success or a negative error code (see nrf_axon_result_e)
