The Jacobian([f(x,y,...), g(x,y,...), ...], [x,y,...]) calling sequence returns the matrix form of the Jacobian. The calling sequence in the form Jacobian([f(x,y,...), g(x,y,...),...], [x,y,...]=[a,b,..]) returns the matrix form of the Jacobian evaluated at a point specified by . The dimension of the point must equal the number of independent variables.

Specifying the option output = method returns the Jacobian in the specified form, where method is one of determinant or matrix. The matrix form is the default.

If the output = determinant option is given, then the number of independent variables must equal the number of algebraic expressions.
