Function dot_subvec (o2scl_cblas)

O2scl : Function List

template<class vec_t, class vec2_t, class fp_t>
fp_t o2scl_cblas::dot_subvec(const size_t N, const vec_t &X, const vec2_t &Y, const size_t ie)

Compute \( r=x \cdot y \) beginning with index ie and ending with index N-1.

This function is used in o2scl_linalg::householder_hv().

If ie is greater than N-1 then the error handler will be called if O2SCL_NO_RANGE_CHECK is not defined.
