Abstract:
MATLAB is a high level programming tool for technical computing, its application cuts across different
sphere of science, engineering, finance, communication, music etc. With the current increase in the use of
non-integer order derivatives, there is a need to have tools that handle them for effective applications. In this
paper, we present a brief comparative review of 2 expressions of fractional derivative. MATLAB functions
for approximating Riemann-Liouville and Caputo fractional derivatives are presented alongside. Numerical
simulations with test examples are implemented and results compared. To effectively handle non-polynomial
function, Taylor series expansion is employed to convert the function into a form that can be easily handled.
