SpectralBoundaryIntegralMethod.m: Spectral boundary integral method code

• This code was developed for part of my dissertation to simulate red blood cell flow using boundary integral methods.
• This repository contains the code for the concepts and examples presented in Chapter 4 for analyzing the red blood cell motion and deformation in an unbounded domain.
