一个很好的matlab源代码——HOSVD，HOSVD算法是通过对张量进行Tucker decomposition后，找出其tensor core,最后对其进行SVD分解。-A good matlab source code SVD, HOSVD algorithm is passed on tensor Tucker decomposition, find out the tensor core, and finally its SVD decomposition.

KKT典型寻优程序，对于目标函数与约束下的程序构造。(KKT typical optimization program, for the objective function and constraints under the program construction.)
