Einstein Convention<br />
• The Einstein Convention, or summation rule<br />
for suffixes looks like this:<br />
A i = B ij C j<br />
where “i” <strong>and</strong> “j” both are integer indexes<br />
whose range is {1,2,3}. So, to find each “i th ”<br />
component of A on the LHS, we sum up over<br />
the repeated index, “j”, on the RHS:<br />
A 1 = B 11 C 1 + B 12 C 2 + B 13 C 3<br />
A 2 = B 21 C 1 + B 22 C 2 + B 23 C 3<br />
A 3 = B 31 C 1 + B 32 C 2 + B 33 C 3
