DeMatrix: 生物分子结构pdb文件的变换矩阵提取程序的源码。pdb文件可显示三维生物分子结构，并且用其他程序显示，显示后可以随意变换，这个程序可以抽取变换的数学矩阵，用于变化同类pdb.-DeMatrix: bio-molecular structure pdb file extraction program source code transformation matrix. pdb file can be displayed three-dimensional structure of biological molecules, and other programs to use a display that can be freely after the change, this program can extract the mathematical transformation matrix for the change in the same pdb.
