The Voigt/complex error function by vectorized interpolation

Program-shell that accelerates computation of the Voigt and complex error functions for the HITRAN applications.

This function file <vecfadf.m> computes the Voigt and complex error functions (also known as the Faddeeva function) in a rapid algorithm by vectorized interpolation. The program is particularly efficient for computation of the large-size input arrays and it meets accuracy requirement for the HITRAN applications. To run the program, download the file <fadsamp.m> from the MATLAB Central, file ID # 66752, and put it to the same folder, where the original function file <vecfadf.m> is located. More information about this algorithmic implementation can be found in [Abrarov et. al., Earth Sci. Res., 8 (2) (2019) 52-63]. URL: https://doi.org/10.5539/esr.v8n2p52
