应用MATLAB编写的三维时域有限差分程序。是初学FDTD的好帮手。建议初学者参考。(Application of MATLAB to prepare three-dimensional finite difference time domain procedure. FDTD are learning a good helper. Recommended reference for beginners.)

这是一个有预测功能的程序，还没有进行优化，可供大家作为基础来加以改进，但是大概的预测方向都是准确的(This is a prediction function of the procedure have not yet optimized for the U.S. used as the basis to be improved, but perhaps the direction of the prediction is accurate)

The important method is [COEFF,SCORE] = princomp(x) which takes in your data “x” and stores its projection into PCA space in “SCORE” which I then output to csv. I still need to find out how to project back into normal space but I think it should be just as straightforward as this was. For more info on “princomp” type “help princomp” into matlab and have a look at the help files.
