TY - JOUR ID - TI - Block and Weddle Methods for Solving nth Order Linear Delay Fredholm Integro-Differential Equations AU - Atheer Jawad Kadhim PY - 2009 VL - 13 IS - 59 SP - 95 EP - 114 JO - journal of the college of basic education مجلة كلية التربية الاساسية SN - 18157467 27068536 AB - A proposed method is presented to solve nth order linear delay Fredholm integro-differential equations (DFIDE's) numerically using fourth-order six stages block and weddle methods. New algorithms with the aid of Matlab language are derived to treat three types (retarded, neutral and mixed) of the first order linear delay Fredholm integro-differential equations using block and Weddle methods and they have been developed to find the numerical evolutions for nth order linear delay Fredholm integro-differential equations. Comparison between the numerical and exact results has been given for numerical examples to solve different types of linear DFIDE's for conciliated the accuracy of the results of the proposed method. Finally, the results are arranged in tabulated form and suitable graphing is given for every example.
