dot

dot multiplication for compaitable vectors.

dot

(

size_t N

size_t K

)

(

auto ref const(Vector!(N, T)) a

auto ref const(Vector!(K, E)) b

)

if (

(

N == K ||

K == 0

N == 0

) &&

hasCompMltAndSum!(T, E)

)

Examples

auto a = vec3(1,2,3);
auto b = vecD(1,2,3);

assert( eq( dot(a,b), 1+4+9 ) );
