We find the wavelet operational matrix of the fractional integration and by using it we transform the fractional differential-algebraic equations to a solvable system of algebraic equations. Two illustrative examples are solved to demonstrate the applicability and validity of the wavelet base technique. The numerical results show that the approximations are in good agreement with the exact solutions and the technique is accurate and easy to implement.eninfo:eu-repo/semantics/closedAccessDifferential Algebraic EquationsFractional Differential-Algebraic EquationsLegendre WaveletsOperational MatrixArticle
