Sort
向量排序，包含升序和降序。
- 整型数的升序排序：
HmppResult HMPPS_SortAscend_8u_I(uint8_t* srcDst, int32_t len);
HmppResult HMPPS_SortAscend_16u_I(uint16_t* srcDst, int32_t len);
HmppResult HMPPS_SortAscend_16s_I(int16_t* srcDst, int32_t len);
HmppResult HMPPS_SortAscend_32s_I(int32_t* srcDst, int32_t len);
- 浮点数的升序排序：
HmppResult HMPPS_SortAscend_32f_I(float* srcDst, int32_t len);
HmppResult HMPPS_SortAscend_64f_I(double* srcDst, int32_t len);
- 整型数的降序排序：
HmppResult HMPPS_SortDescend_8u_I(uint8_t* srcDst, int32_t len);
HmppResult HMPPS_SortDescend_16u_I(uint16_t* srcDst, int32_t len);
HmppResult HMPPS_SortDescend_16s_I(int16_t* srcDst, int32_t len);
HmppResult HMPPS_SortDescend_32s_I(int32_t* srcDst, int32_t len);
- 浮点数的降序排序：
HmppResult HMPPS_SortDescend_32f_I(float* srcDst, int32_t len);
HmppResult HMPPS_SortDescend_64f_I(double* srcDst, int32_t len);

示例
#define BUFFER_SIZE_T 9
void Sort_Example() {
uint8_t src[BUFFER_SIZE_T] = {255, 0, 254, 0, 253, 1, 252, 2, 251};
int32_t i;
HmppResult result = HMPPS_SortAscend_8u_I(src, BUFFER_SIZE_T);
if (result == HMPP_STS_NO_ERR) {
printf("result = %d\n", result);
printf("dst = ");
for (i = 0; i < BUFFER_SIZE_T; i++) {
printf("%d ", src[i]);
}
printf("\n");
}
}
运行结果：
result = 0 dst = 0 0 1 2 251 252 253 254 255
