• "contract(Matrix,Number)" -- see contract(Matrix,Matrix) -- contract a matrix by a matrix
• "contract(Matrix,RingElement)" -- see contract(Matrix,Matrix) -- contract a matrix by a matrix
• "contract(Matrix,Vector)" -- see contract(Matrix,Matrix) -- contract a matrix by a matrix
• "contract(Number,Matrix)" -- see contract(Matrix,Matrix) -- contract a matrix by a matrix
• "contract(Number,Number)" -- see contract(Matrix,Matrix) -- contract a matrix by a matrix
• "contract(Number,RingElement)" -- see contract(Matrix,Matrix) -- contract a matrix by a matrix

For the programmer

The object contract is a method function.
