Another solution is given here > [@Inverse of a (m,m)-Matrix whose elements are (n,n)-Matrices](https://wolfram.discourse.group/t/14429/1): > > By Albrecht Küster ([hcak@gmx.de](mailto:hcak@gmx.de)) and Hans Dolhaine ([h.dolhaine@gmx.de](mailto:h.dolhaine@gmx.de)) In a foregoing post [https : // community.wolfram.com/groups/-/m/t/1651695?p\_p \_auth = EmJqMz34](http://https%20:%20//%20community.wolfram.com/groups/-/m/t/1651695?p_p%20_auth%20=%20EmJqMz34) Stan Gianzero asked, how the inverse of a 2 x 2 matrix, whose elements are 2 x 2 matrices themselves might be found. In that post an answer was given and Stan's problem solved. But this anwer is highly specialized, because all the elements of the given matrix must be regular ( = non-singular) and moreover certain functions o… [wcomABdivmat.nb](https://community.wolfram.com/uploads/short-url/bFBT3vtANedToEYxSRhQHq8cc6x.nb) (367 KB) --- _[View the full topic](https://community.wolfram.com/t/flatten-array-without-loosing-structure/19879)._
