GDIQ is an acronym for Generalized Differential and Integral Quadrature. The purpose of this tool is to provide a general framework for calculating the derivatives (up to the fourth order) and integrals for a general function. GDIQ Tool is one of the activities of CIMEST Research Centre. This code allows the user to experience interactively the functional approximation of derivatives and integrals.

The theoretical implementation of the present software has been performed following the mathematical background presented in the books:
