| FwStatus | fwsArctan_32f | ( | const Fw32f * pSrc, Fw32f * pDst, int len ); | |
| FwStatus | fwsArctan_64f | ( | const Fw64f * pSrc, Fw64f * pDst, int len ); | |
| FwStatus | fwsArctan_32f_I | ( | Fw32f * pSrcDst, int len ); | |
| FwStatus | fwsArctan_64f_I | ( | Fw64f * pSrcDst, int len ); |
| len | Specifies the number of elements in a buffer. | |
| pDst | Pointer to a destination buffer. | |
| pSrc | Pointer to a source buffer. | |
| pSrcDst | Pointer to a buffer that is both the source and destination. |
These functions step through vector elements in a source buffer and calculate the inverse tangent of each element.
Results can be written to a destination buffer or written back to the source buffer.
