I would like to create an $m \times n$-table
A with entries
Ai_j, where $1 \leq i \leq m$ and $1 \leq j \leq n$. I have seen similar questions with subscripts, but I need the entries to be exactly of the form
Ai_j, since I'm importing data from MatLab.
To be more specific, I have a list of equations with variables
Ai_j from Matlab and I want to solve them with Mathematica. For this I need to specify for which variables to solve, but I'm to lazy to type them in one-for-one (its a huge matrix) so I just wanted to use
As written in the comments, another option would be to transport the matrix
A=sym('A',[m,n]) from Matlab to Mathematica, but I don't know how either.
