Section: High level matrix functions

Name: vecprod

Calculate the scalar product of two vectors.
Special case of matrix row by column multiplication:
a * b T


[ c:'a ] = vecprod
a:('a, 'b, 'c) Matrix.t
b:('a, 'd, 'e) Matrix.t

Examples: 
[] let a = imatrix ~const:[1;2;3] ();; 
val a : (int, '_a, '_b) Matrix.t = <abstr> 
[] let b = imatrix ~const:[-1;2;-3] ();; 
val b : (int, '_a, '_b) Matrix.t = <abstr> 
[] let v = vecprod a b ;; 
val v : int = -6 
[] let v = a <.*.> b ;; (* shortcut *) 
val v : int = -6
