本资源为基于Matlab的数字图像相关法（DIC）代码版本1.130814，适用于分析材料力学实验中的散斑图案，用于应变和位移测量。
Digital Image Correlation (DIC) is an optical, non-contact technique for measuring full-field displacements and strains. The only requirement is that the test specimen must have a random speckle pattern on its surface, which can be either artificially created by the experimenter or naturally occurring. DIC has no inherent length scale; through appropriate selection of image magnification and speckle size, it can measure displacements ranging from meter to micron scales.
