Abstract

Non-polynomial spline functions of the form Span{1, x, x2; x3; x4; x5; cosðkxÞ þ exg,
where k can be real or pure imaginary, are used to find the numerical solution of linear fifth-order
boundary value problems. The order of convergence of the method is observed to be of Oðh2
Þ. A
fifth order convergent method is defined with the help of improved end-conditions. Three examples
are considered to show the reliability and efficiency of the method. The numerical results, obtained,
endorse the improved order of convergence of the method.
