I am trying several methods to achieve best results for both accuracy and calculation time wise for different size and loop of matrices. However I couldn't find a document for how inv() function implemented in matlab itself works.

The INV documentation states "inv performs an LU decomposition of the input matrix (or an LDL decomposition if the input matrix is Hermitian). It then uses the results to form a linear system whose solution is the matrix inverse inv(X)"
