Inverse Matrix

You could actually get the inverse of a given matrix, as long as the dimensions of a matrix is the same $(2$x$2$, $3$x$3$, $69$x$69,$ etc.$)$. Inverse matrices only exist if the matrix is a square matrix...

But for me, I could get the inverse matrix of a 2x2, 3x3 and 4x4 matrix reliably, but realistically, we could get the inverse of any square matrix.

But I don't know how to get inverse matrix of square matrix have many dimensions, hehe
