Data Type |
Description |
Value Range |
|---|---|---|---|
dis |
float* |
Stores the distance computation result. |
The size is specified by dis_size. The memory needs to be allocated in advance. |
x |
const uint16_t* |
Query vector for distance computation. |
The vector has a dimension of d. |
y |
const uint16_t* |
Base vector for distance computation. |
The size is specified by d × ny. |
ids |
const int64_t* |
IDs of base vectors. |
The ID value is greater than or equal to 0 and less than the total number of base vectors. |
d |
size_t |
Vector dimension. |
[1, 65535] |
ny |
size_t |
The number of base vectors. |
[1, 2^30 − 1] |
dis_size |
size_t |
Specifies the size of the distance result array. |
The value is specified by ny. |
