Provide numeric field designatoors for each element in the unit vectors (I added the square brackets, remove them if yoou don’t want them) —
a = [1 2 3];
b = [4 5 6];
ua=a./norm(a);
ub=b./norm(b);
d=dot(a,b);
c=cross(a,b);
sum=a+b;
di=a-b;
fprintf('the unit vector of a is [%0.3f %0.3f %0.3f]\n',ua)
fprintf('the unit vector of b is [%0.3f %0.3f %0.3f]\n',ua)
fprintf('the dot product a.b= %0.3f and the cross product axb= %0.3f \n',d , c)
fprintf('the sum of a+b= %0.3f and the difference of a-b= %0.3f \n',sum , di )
.
