How can we find the generic element of the Kronecker product of two matrix: Let $A=(a_{ij})_{{1\leq i\leq n}, {1\leq j\leq p}}$ and $n\times p$ matrix and $B=(b_{ij})_{{1\leq i\leq m}, {1\leq j\leq q}}$ and $m\times q$ matrix. The Kronecker product of $A$ and $B$ is defined as: $$ A\otimes B=\left( \begin{array}{ccc} a_{11}B & \cdots & a_{1p}B \\ \vdots & & \vdots \\ a_{n1}B & \cdots & a_{np}B \end{array} \right) $$ So, $A\otimes B$ is an $nm \times pq$ matrix. How we can point out the generic element $(A\otimes B)_{k\ell}$ for $k\in \{1, \dots, nm\}$ and $ \ell \in \{1, \dots, pq\}$ using the Euclidean division of $k$ and $\ell$.
A lot of thanks to your help.
Well, i was also stuck into this problem since few days during my research and finally got the solution.. The generic element of a kronecker product of A (LxL) and B (MxM) can be expresses as follows
(A kron B)_{i,j} = A(ceil(i/M, j/M))*B((i,j))M
where ((.)) is mod operation
hope this would help.
