SHEEP SHEEP is a computer algebra system designed primarily for the needs of General Relativity, but it can also be used in other fields. SHEEP can: Read, write, simplify, substitute into and differentiate algebraic expressions. Define tensors and tensor algorithms. Manipulate tensor components. Calculate the Einstein tensor from a given metric in a tetrad or in a coordinate frame.
