Assume that matrix $A$ define in this form $A=[a_{ijk}] , a_{ijk} \in F$ ($F$ is arbitrary field ).
The size of $A$ is $m \times n \times k$ ($m$ is number of row and $n$ is number of column and $k$ is number of vector that is perpendicular on row vector and column vector ) . May I ask you to hint me about the following:
a)How can I define determinate ?
b) how can I solve system of linear equation $(AX=b )$?
Or let this matrix is $A=[a_{(i_1,i_2,..,i_n )}]$ (all entry is from $Ν×Ν×…×Ν$ to $F$ s.t $(i_1,i_2,..,i_n)→ a_{(i_1,i_2,..,i_n )}$ and define size of matrix like above, can we compute $a$ and $b$ for this matrix?
Thanks so much!
