template<unsigned n, unsigned N, class E> Vec<N,_DETAIL_> splat( const Vec<N,E>& a );

Broadcasts n-th element of the source vector across all lanes of the vector.

Vec must be a non-mask vector type.

Parameters

a	-	source vector
n	-	the index of the element to broadcast

Return value

A vector with all elements set to the n-th element.

Equivalent operation

r0 = a[s]
r1 = a[s]
...
rM = a[s]

Here M = N-1.
