Representation of a gradient for scalar electromagnetic field in MATLAB using differential operators

In this work, the representation of an algorithm was deduced and developed in MATLAB, to calculate an electromagnetic scalar field utilizing differential operators to generate graphics about the electromagnetic spectrum, the distance X,Y of the field curvature, as well as the gradient example of the electromagnetic field. The main objective of this article is to compare the new GUI features of the algorithm developed in MATLAB to the previous algorithm as cited in the previous work of this paper, showing also the spectrum average of this new algorithm can reach, according to the differential operators values inserted into the code
