The code plots the stress field along x direction due to a cuboid strain located in the center of coordinates system in an Infinite Space. The matlab file reproduces a plot from paper: "On the stress field due to initial strains in a cuboid Surrounded by an Inifinte Elastic Space", Chiu, 1977. It is useful in construction of 3D FFT based algorithm for calculation of elastic stress field due to initial strains (or residual, thermal, etc.).
