Hello,

I have 20 by 20 matrix (with only two symbolic components, say a and b), other entries of the matrix are either populated with zeros or real numbers. I am trying to obtain the inverse.

 

All the command I have tried returned an error message. In particular M^(-1) yields:

Error, (in radnormal/ifactors) too many levels of recursion.

 

I would appreciate any suggestion that could solve this issue. Thank you

 

ps: I am essentially trying to solve Ax=b. The commands within LinearAlgebra all yielded similar error messages.
