Fuzzy C-means Matleb source code

根据华为5G创新大赛polar code部分提供的材料编写的polar code仿真代码，包含SC、SCL、BP三种译码算法。代码实现过程和所提供的材料保持高度一致，便于理解。(According to the Huawei 5G Innovation Competition Polar Code part ,the code is including SC and SCL two decoding algorithms. The code implementation process is highly consistent with the material provided and is easy to understand.)

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)
