梯度下降求解逻辑回归

构造一组输入为白噪声加三个频率非常接近的正弦波，其信噪比为10dB，观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率，并比较结果。-constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used to test the general AR spectral estimation using power and noise canceling algorithm for the estimation of AR spectrum estimation of this group of signal frequency, and the results of the comparison.

说明：  采用IDL语言，可以用来动态监测水体变化，输入影像即可(Monitoring water body changes by remote sensing)

进制转换的一个很好的函数。可在16进制内自由转换，也可创新地使用5、6、7等进制格式。经过简单改造后可使用最大36进制的形式。是编程人员的一个好东东。-base for the conversion of a good function. 16 in the 229 free conversion, but also innovative use of 5, 6, 7, etc.-band format. After simple transformation can be used after the 36 largest 229 forms. Programming staff is a good Eastern.
