The author presents a versatile MATLAB software package capable of solving both single and systems of ordinary differential equations (ODEs). The software is implemented as a MALTAB app package, that should be installed before the use. Allowing users to efficiently handle and solve ODE problems using classical, caputo, and ABC approaches of fractional calculus. The app offers two powerful numerical schemes: the Euler method and the fourth-order Runge-Kutta method, providing flexibility and accuracy for various ODE scenarios. With this code, researchers and practitioners can seamlessly explore and analyze dynamic systems, making it a valuable tool for advancing scientific investigations in diverse fields. There are two files: sinan.mlappinstall test.mlx sinan.mlappinstall is the MATLAB app to install, while test.mlx is the script file that can show the tutorial how to call the numerical solvers.
