The Algebraic Tool can perform basic algebraic functions, such as derivatives and integrals, on a fitted expression generated by the Fitting Tool. The resulting equation can be plotted in the current graph, tagged in, or be copied to clipboard (in latex format).
Performing an integral over a 2D fitted equation of effective mode index (neff) as a function of the waveguide width (W[nm]) and wavelength (λ[nm]). The result is the explicit equation obtained underneath in blue.
