problem comes from "Numerical solution of fractional integro-differential , equations by collocation method , E.A. Rawashdeh, Department of Mathematics, Yarmouk University, Irbid 21110, Jordan"
$D^qy(t)=p(t)y(t)+f(t)+\int_{0}^{1}{K(t,s)y(s)\,ds} , t\in I=[0,1]$
I want to create a maple code to check if the results in given article is valid or not but I do not have any idea about collocation method!
any reference to collocation method solution are welcome!
