The discussion centers on the need for open source code or guidance on coding the propagation of multi Gaussian beams through multiple interfaces using the ABCD matrix approach in the context of ultrasound, rather than optics. A referenced article suggests using MATLAB for modeling, and participants recommend researching the authors for potential access to the MATLAB code. A related presentation is also mentioned, although it is noted that it may not provide significant assistance. Participants suggest contacting the authors directly for open source code or, alternatively, advise that understanding the manual process is essential for developing the code independently. Writing the program involves documenting the steps taken and refining them for clarity and functionality.
