This is a MATLAB 3D-volumetric finite-element-based DVC code I wrote to compare with our newly proposed ALDVC algorithm [1,2].
% =========================================
% Installation
FE_Global_DVC MATLAB code was tested on MATLAB versions later than R2018a. Please download and unzip the code to the MATLAB working path. Then, execute the mail file main_FE_Global_DVC.m.

[2] Welcome to compare this code with our proposed ALDVC code, which combines both advantages of Local Subvolume DVC (fast, compute in parallel) and Global DVC (guarantee kinematic compatibility, see https://www.mathworks.com/matlabcentral/fileexchange/77019-augmented-lagrangian-digital-volume-correlation-aldvc.
[3] % ===================================
% ****** ATTENTION ******
% The "x,y,z" or "1-,2-,3-" coordinates in the ALDVC code always correspond to the 1st, 2nd and 3rd indices of Matlab workspace variable. For example, p_meas(:,1) and p_meas(:,2) are the x- & y-coordinates of scattered points.
%
% This is a little different from some MATLAB image processing functions. % For example, if a 3D image has size MxNxL, in this code, we always have the image size_x=M, size_y=N, size_z=L. If you use some Matlab computer vision/image post-processing function, for example, 'imagesc3D', or 'imshow3D', or 'surf', it will reads size_x=N, size_y=M, size_z=L.
