You can factorize the matrix using LU or LDLT factorization algorithm. inverse of a diagonal matrix (D) is really simple. To find the inverse of L, which is a lower triangular matrix, you can find the answer in this link.

Since (A T )-1 = (A-1 )T for all matrix, you'll just have to find inverse of L and D.

it is used to find the inverse of the matrix. inverse(A)= (adj A)/ mod det A
Let A be a matrix which is both symmetric and skew symmetric. so AT=A and AT= -A so A =- A that implies 2A =zero matrix that implies A is a zero matrix

The fact that the matrix does not have an inverse does not necessarily mean that none of the variables can be found.
A skew symmetric matrix is a square matrix which satisfy, Aij=-Aji or A=-At
If your graph is undirected, then its adjacency matrix will be symmetric. Faizan
A non-square matrix cannot be inverted.
Symmetric Matrix:Given a square matrix A such that A'=A, where A' is the transpose of A, then A is a symmetric matrix.note: No need to think about diagonal elements, they can be anything.
To find the original matrix of an inverted matrix, simply invert it again. Consider A^-1^-1 = A^1 = A
The fx-991MS lacks the inverse operator so the matrix inverse is not possible, Try 991Es instead
The eigen values of a real symmetric matrix are all real.
