AbdelAty, A. M.; Fouda, M. E.; Eltawil, A. M. Comment on “FPGA realization of fractional order neuron”. (English) Zbl 1481.92025 Appl. Math. Modelling 92, 951-954 (2021). Summary: This paper points out a number of mathematical inaccuracies in the recent paper [ibid. 81, 372–385 (2020; Zbl 1481.92027)] by S. A. Malik and A. H. Mir. The comments in this paper pertain mainly with the errors presented in Section 3 of that paper referencing the discretization of the fractional operator. Proposed corrections to the formulas and figures are presented along with a sample Maple code to verify the results.
