tensor multiplication according to Einstein summation convention
Description
This function computes a tensor product according to Einstein summation convention
Syntax
% sumation against dimension 1 and 2
C = EinsteinSum(E,[1 -1 2 -2],v,-1,v,-2)eps = EinsteinSum(C,[-1 1 -2 2],sigma,[-1 -2])Input
| T1,T2 | tensor |
| dimT1 | vector of indices giving the summation order in tensor 1 |
| dimT2 | vector of indices giving the summation order in tensor 2 |
Output
| T | tensor |
