Hi,
I use inv function in my code to solve a square matrix inversion and a lower triangular matrix inversion. May I know what is the inversion method used in MATLAB to solve this inversion?

"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). For sparse inputs, inv(X) creates a sparse identity matrix and uses backslash, X\speye(size(X))."
