(D)SDOT¶

Double with extended internal precision SDOT.

Description¶

Performs a dot product of the input vectors X and Y using extended internal precision for accumulation.

$\result = \sum_{i=1}^N {x_{i} \mult y_{i}}$

double dsdot(const qml_long *N, const float *X, const qml_long *INCX,
             const float *Y, const qml_long *INCY);

double cblas_dsdot(const qml_long N, const float *X, const qml_long INCX,
                   const float *Y, const qml_long INCY);

N	Number of elements in X and Y
X	First input vector, must be at least: $(\fvar{N}-1)\mult\abs{\fvar{INCX}} + 1$
INCX	Distance between individual elements in X
Y	Second input vector, must be at least: $(\fvar{N}-1)\mult\abs{\fvar{INCY}} + 1$
INCY	Distance between individual elements in Y
Result	Result of the dot product
