Computes inverse square root of vector elements.
Syntax
IppStatus ippsInvSqrt_32s_I (Ipp32s* pSrcDst, int len);
Parameters
pSrcDst |
Pointer to the source and destination vector. |
len |
Number of elements in the vector. |
Description
The function ippsInvSqrt is declared in the ippsc.h file. This function computes the inverse square roots as:
using the approximation table. The input and output vectors are scaled by 30 bits.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when the pSrcDst pointer is NULL. |
ippStsSizeErr |
Indicates an error when len is less than or equal to 0. |
