While 1D finite element programs are relatively straightforward, 2D finite element source codes present significant complexity. This MATLAB program solves two-dimensional elliptic equations using rectangular grid discretization, featuring robust implementation that generates both exact and numerical solution visualizations. The program serves as both an elliptic equation solver and a reference implementation for other PDEs, requiring only minor modifications to adapt to different equations. Key algorithmic components include mesh generation, stiffness matrix assembly, and variational formulation implementation.

This program provides a MATLAB simulation of the correlation interferometer direction finding technique. Utilizing a 5-element circular antenna array as the receiving array, it calculates phase differences between antenna pairs to build a reference pattern library and determines signal direction of arrival through correlation processing. Execute untitled1.m and input relevant parameters to demonstrate the functionality. The implementation includes phase difference computation, covariance matrix generation, and peak detection algorithms for direction estimation.
