v?sqr
Interface Definition
C interface:
void vssqr(const int len, const float* src, float* dst);
void vdsqr(const int len, const double* src, double* dst);
Fortran interface:
CALL VSSQR(LEN, SRC, DST);
CALL VDSQR(LEN, SRC, DST);
Parameters

Type |
Description |
Input/Output |
|---|---|---|---|
len |
Integer |
Number of elements in the input vector. If len ≤ 0, the system displays a message indicating that the value of len is invalid. |
Input |
src |
|
Input vector src with length len. If the pointer is null, the system prompts a null pointer error. |
Input |
dst |
|
Output vector dst with length len. If the pointer is null, the system prompts a null pointer error. |
Output |
Return Value
The square of a number is returned for each operation value. The value range is [0, +INF).
Input Value (src) |
Output Value (dst) |

Examples
C interface:
int i, len = 4;
float src[len] ={0.0f, 0.5f, 1.0f, 5.0f]};
float* dst = (float*)malloc(sizeof(float) * len);
if (dst == NULL) {
printf("Malloc Failed!\n");
return 0;
}
vssqr(len, src, dst);
