Normalize

使用偏移和除法运算对实数或复数向量的元素进行归一化，本函数归一化采用将向量的数值平移和缩放到一个范围，即线性归一化。

向量归一化处理。计算公式为：。

对于原址操作函数，计算公式为：。

函数接口声明如下：

• 浮点数的操作：

  HmppResult HMPPS_Normalize_32f(const float *src, float *dst, int32_t len, float sub, float div);

  HmppResult HMPPS_Normalize_64f(const double *src, double *dst, int32_t len, double sub, double div);

  HmppResult HMPPS_Normalize_32fc(const Hmpp32fc *src, Hmpp32fc *dst, int32_t len, Hmpp32fc sub, float div);

  HmppResult HMPPS_Normalize_64fc(const Hmpp64fc *src, Hmpp64fc *dst, int32_t len, Hmpp64fc sub, double div);

• 浮点数的原址操作：

  HmppResult HMPPS_Normalize_32f_I(float *srcDst, int32_t len, float sub, float div);

  HmppResult HMPPS_Normalize_64f_I(double *srcDst, int32_t len, double sub, double div);

  HmppResult HMPPS_Normalize_32fc_I(Hmpp32fc *srcDst, int32_t len, Hmpp32fc sub, float div);

  HmppResult HMPPS_Normalize_64fc_I(Hmpp64fc *srcDst, int32_t len, Hmpp64fc sub, double div);

• 有缩放的整型数操作：

  HmppResult HMPPS_Normalize_16s_S(const int16_t *src, int16_t *dst, int32_t len, int16_t sub, int32_t div, double scale);

  HmppResult HMPPS_Normalize_16sc_S(const Hmpp16sc *src, Hmpp16sc *dst, int32_t len, Hmpp16sc sub, int32_t div, double scale);

• 有缩放的整型数原址操作：

  HmppResult HMPPS_Normalize_16s_IS(int16_t *srcDst, int32_t len, int16_t sub, int32_t div, double scale);

  HmppResult HMPPS_Normalize_16sc_IS(Hmpp16sc *srcDst, int32_t len, Hmpp16sc sub, int32_t div, double scale);

#define BUFFER_SIZE_T 10

void NormalizeExample(void)
{
    float src[BUFFER_SIZE_T] = {3, 0, 2, -8, 3, 1, 7, 5, -2, 1};
    float dst[BUFFER_SIZE_T];
    float sub = 3;
    float div = 5;
    HmppResult result;
    result = HMPPS_Normalize_32f(src, dst, BUFFER_SIZE_T, sub, div);
    printf("result = %d\n", result);
    if (result != HMPP_STS_NO_ERR) {
        return;
    }
    printf("dst =");
    for (int i = 0; i < BUFFER_SIZE_T; i++) {
        printf(" %.1f", dst[i]);
    }
    printf("\n");
}

result = 0
dst = 0.0 -0.6 -0.2 -2.2 0.0 -0.4 0.8 0.4 -1.0 -0.4
