For this purpose, we divide the time interval of the problem into some nonequal subintervals and define a piecewise interpolating polynomial on the base of transformed Legendre-Gauss nodes in subintervals. According to the weak representations approach, we derive the corresponding operational matrix of derivative. Using the Legendre-Gauss quadrature formula and the obtained operational matrix, the optimal control problem is discretized as a nonlinear
