Is it possible to conduct MATLAB operations on just a matrix of variables? For example, if I wanted to compute the inverse of matrix
A = [a b; c d]
without assigning any values to any of the 4 variables just to get a general form. Thanks in advance!

Caution: the size of the matrix expands quite rapidly for larger matrices.
