## Member Function Documentation

## ◆ get0()

template<typename _Tp , int n>

_Tp cv::v_reg< _Tp, n >::get0 | ( |  | ) | const
| inline

Access first value.

Returns value of the first lane according to register type, for example:

v_int32x4 r(1, 2, 3, 4);
int v = r.get0(); // returns 1
v_uint64x2 r(1, 2);
uint64_t v = r.get0(); // returns 1
