SubCRev

常量与向量相减。

函数接口声明如下：

• 浮点数的操作：

  HmppResult HMPPS_SubCRev_32f(const float *src, float val, float *dst, int32_t len);

  HmppResult HMPPS_SubCRev_64f(const double *src, double val, double *dst, int32_t len);

  HmppResult HMPPS_SubCRev_32fc(const Hmpp32fc *src, Hmpp32fc val, Hmpp32fc *dst, int32_t len);

  HmppResult HMPPS_SubCRev_64fc(const Hmpp64fc *src, Hmpp64fc val, Hmpp64fc *dst, int32_t len);

• 整型数的缩放操作：

  HmppResult HMPPS_SubCRev_16s_S(const int16_t *src, int16_t val, int16_t *dst, int32_t len, int32_t scale);

  HmppResult HMPPS_SubCRev_32s_S(const int32_t *src, int32_t val, int32_t *dst, int32_t len, int32_t scale);

  HmppResult HMPPS_SubCRev_8u_S(const uint8_t *src, uint8_t val, uint8_t *dst, int32_t len, int32_t scale);

  HmppResult HMPPS_SubCRev_16u_S(const uint16_t *src, uint16_t val, uint16_t *dst, int32_t len, int32_t scale);

  HmppResult HMPPS_SubCRev_16sc_S(const Hmpp16sc *src, Hmpp16sc val, Hmpp16sc *dst, int32_t len, int32_t scale);

  HmppResult HMPPS_SubCRev_32sc_S(const Hmpp32sc *src, Hmpp32sc val, Hmpp32sc *dst, int32_t len, int32_t scale);

• 浮点数的原址操作：

  HmppResult HMPPS_SubCRev_32f_I(float val, float *srcDst, int32_t len);

  HmppResult HMPPS_SubCRev_64f_I(double val, double *srcDst, int32_t len);

  HmppResult HMPPS_SubCRev_32fc_I(Hmpp32fc val, Hmpp32fc *srcDst, int32_t len);

  HmppResult HMPPS_SubCRev_64fc_I(Hmpp64fc val, Hmpp64fc *srcDst, int32_t len);

• 整型数的原址缩放操作：

  HmppResult HMPPS_SubCRev_16s_IS(int16_t val, int16_t *srcDst, int32_t len ,int32_t scale);

  HmppResult HMPPS_SubCRev_32s_IS(int32_t val, int32_t *srcDst, int32_t len ,int32_t scale);

  HmppResult HMPPS_SubCRev_8u_IS(uint8_t val, uint8_t *srcDst, int32_t len, int32_t scale);

  HmppResult HMPPS_SubCRev_16u_IS(uint16_t val, uint16_t *srcDst, int32_t len, int32_t scale);

  HmppResult HMPPS_SubCRev_16sc_IS(Hmpp16sc val, Hmpp16sc *srcDst, int32_t len, int32_t scale);

  HmppResult HMPPS_SubCRev_32sc_IS(Hmpp32sc val, Hmpp32sc *srcDst, int32_t len, int32_t scale);
