Jwamer AJAMS2013133 10.12691/ajams-1-3-3 2013 03 29 2013 06 09 2013 06 11 This paper surveys and reviews paper of spline degree seven inhomogeneous and optimized the best errors bound by spline (0,2, 5; 0, 3, 6) case. It has been shown that the existence, uniqueness and convergence analysis with minimizing the error bounds of deficient seventh spline interpolated.
