Abstract
This Paper presents the design and Implementation of a Numerical Model for solving ordinary differential equations with Initial values. It was a resultant equation of Gompertz and Logistic models. Some problems were solved successfully to test the accuracy, performance and suitability of the Model in terms of the absolute relative errors computed via MATLAB codes. The numerical solutions obtained via the Model agreed with the analytical solutions of the problems that were examined. The analysis of the properties of the method such as consistency, stability and convergence were also investigated. It was found to converge, be consistent and very stable. The combinations of Gompertz and Logistic Models as the basis function makes the work an improvement of existing methods used to evaluate growth problems and IVPs of various areas of Ordinary Differential Equations (ODEs).
