Parameters
pSrc |
Pointer to the source vector. |
pNorm |
Pointer to the output result. |
len |
Number of elements in the vector. |
scaleFactor |
Scale factor, refer to Integer Scaling. |
Description
This function computes the C, L1, L2, or L2Sqr norm of the source vector pSrc and stores the result in pNorm.
ippsNorm_Inf.The function ippsNorm_Inf computes the C norm defined by the formula:
ippsNorm_L1. The function ippsNorm_L1 computes the L1 norm defined by the formula:
ippsNorm_L2. The function ippsNorm_L2 computes the L2 norm defined by the formula:
ippsNorm_L2Sqr. The function ippsNorm_L2Sqr computes the L2Sqr norm defined as square of the L2 norm.
Functions with Sfs suffixes perform scaling of the result value in accordance with the scaleFactor value.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when the pSrc or pNorm pointer is NULL. |
ippStsSizeErr |
Indicates an error when len is less than or equal to 0. |
