2 dp - dot product of two vectors
8 x, y 1-dimensional matrices of the same size
10 return depends on the nature of the elements of x and y
13 Compute the dot product of two 1-dimensional matrices.
20 Then dp(x,y) returns the result of the calculation:
22 x0*y0 + x1*y1 + ... + xn*yn
26 ; mat y[1:3] = {3,4,5}
34 VALUE matdot(MATRIX *x, MATRIX *y)
