Einstein Sommation like Numpy's einsum
Input :
- str : String like 'ik,kj-> ij'
- varargin : Double called
Output :
- Out : Double
Usage :
Matrix multiplication C = A*B
A(ik)*B(kj) = C(ij) -> C=einsum('ik,kj->ij',A,B)
Limitations :
- Taking "diagonal terms" for an nd-array isn't permitted
ex : 'iij,jk -> ik'
- Be careful about approximation error
ex : Doing A^12 with einsum gives you a N_inf(relative_error) around 1E-10
