Computes a dot product of a conjugated vector with another vector.
Syntax
void cblas_cdotc_sub (const MKL_INT n, const void *x, const MKL_INT incx, const void *y, const MKL_INT incy, void *dotc);
void cblas_zdotc_sub (const MKL_INT n, const void *x, const MKL_INT incx, const void *y, const MKL_INT incy, void *dotc);

Description
The ?dotc routines perform a vector-vector operation defined as:
where xi and yi are elements of vectors x and y.
Input Parameters
- n
Specifies the number of elements in vectors x and y.
- x
Array, size at least (1 + (n -1)*abs(incx)).
- incx
Specifies the increment for the elements of x.
- y
Array, size at least (1 + (n -1)*abs(incy)).
- incy
Specifies the increment for the elements of y.
Output Parameters
- dotc
Contains the result of the dot product of the conjugated x and unconjugated y, if n is positive. Otherwise, it contains 0.
