Augmented Lagrangian Digital Image Correlation (2D_ALDIC)

AL-DIC(Augmented Lagrangian DIC) is a fast, parallel-computing hybrid DIC algorithm, which combines advantages of local subset DIC method (fast computation speed, and parallel computing) and finite-element-based global DIC method (guarantee global kinematic compatibility and decrease noise).

Welcome to give the ALDIC code ratings and comments in the MATLAB File Exchange community:

Advantages of AL-DIC algorithm

Prerequisites & Installation

AL-DIC MATLAB code was tested on MATLAB versions later than R2018a. Both single thread and parallel computing features are included in AL-DIC code. Please download and unzip the code to the MATLAB working path. Then, execute the mail file: main_ALDIC.m.
