You will need to use the symbolic toolbox to get the exact result. You will need to pass exact inputs into the symbolic eig function, so you will need to determine what the exact value is that corresponds to each of your floating point inputs. For example is 1.23 exactly 123/100 or is 1.23 representing the range 1225/1000 inclusive to 1235/1000 exclusive? Only if you have exact inputs can you hope to get out an exact result.
