krl_L2sqr_ny_with_handle
Interface Definition
int krl_L2sqr_ny_with_handle(const KRLDistanceHandle* kdh, float* dis, const float* x, size_t dis_size, size_t x_size);
Function
Performs one-to-many Euclidean distance computation on vectors represented in float precision. The base vectors and dimensions are stored in the handle.
Parameters

Description |
Value Range |
|---|---|---|---|
kdh |
const KRLDistanceHandle* |
Pointer to a KRLDistanceHandle instance. |
It cannot be null, and is initialized using krl_create_distance_handle. |
dis |
float* |
Stores the distance computation result. |
The size is specified by dis_size. The memory needs to be allocated in advance. |
x |
const uint8_t* |
Query vector for distance computation. |
The size is specified by x_size. |
dis_size |
size_t |
Size of the distance result array. |
The size is specified by num_base x codes_num, where num_base is the number of query vectors processed in a single batch, and codes_num is the number of base vectors each query vector is compared against. |
x_size |
size_t |
Specifies the size of the query vector array. |
The size is specified by d x num_base, where d is the vector dimension. |
