• General orthogonal polynomials
• Multidimensional piecewise

Multidimensional general orthogonal polynomials and its operator are proposed. Their basic properties and operational rules are set up in a systematic way. Two-dimensional general orthogonal polynomials operator method is applied to the parameter identification of a kind of nonlinear distributed parameter systems. The numerical example shows that a better result under the measuring noise can be obtained, even using fewer numbers of piecewise and orthogonal basis.
