针对多层导热特性的一个简单分析模型，可通过对不同层材料特性的设置，核算材料温度的变化。 (A simple model for the analysis of the thermal properties of the multilayer may be provided by the material properties of the different layers, accounting material temperature variations.)

esprit算法是进行高分辨阵列测向地基本算法，它与music算法不同的是它不用进行谱搜索，大大的节省了时间(esprit algorithm is to carry out high-resolution array geotropism test the basic algorithm, it is different music algorithm is its need for spectrum search, significantly saving time)

卷积码的编码和译码的matalb程序，译码算法采用viterbi算法(Convolutional encoding and decoding matalb procedures decoding viterbi algorithm using)

说明：  Turbo码的BCJR 算法 将通过观察离散无记忆信道(DMC) 中的M arkov 信源的接收序列, 经过计算, 给出每符号(状态) 最小 差错概率的符号(状态) 序列。(Turbo Codes BCJR algorithm by observing without discrete memory accesses (DMC), M arkov source reception sequence, calculated, given every sign (state), the smallest error probability of symbols (state) sequence.)

扩散系统之浓度分布的装置。管中储放静止液体B，高度为L=10 ㎝，放置于充满A 气体的 环境中。假设与B 液体接触面之浓度为3 C 0 0.01mol m A = ，且此浓度不随时间改变 而改变，即在操作时间内( h = 10天)维持定值。气体A 在液体B 中之扩散系数为 D m s AB = 2×10− 9 2 。试决定以下两种情况下，气体A溶于液体B中之流通量(flux)。 (a) A 与B 不发生反应； (b) A 与B 发生以下之反应 A+ B→C ， A A − r = kC 其反应速率常数k = 2×10− 7 s− 1。 (Diffusion system of concentration reference device shown in Figure 3. Tube in the store still liquid B, L = 10 cm height, placed in full A gas environment. Assuming the contact surface of the liquid with the B concentration of 3 C 0 0.01mol m A =, and this concentration does not change with time and change, that is, the operating time (h = 10 days) to maintain constant. Gas A in liquid B, the diffusion coefficient D ms AB = 2 × 10-9 2. Decided the following two test cases, the gas dissolved in liquid B in the A liquid (flux). (A) A and B do not react (b) A and B of the following reaction occurs A+ B → C, AA- r = kC, the reaction rate constant k = 2 × 10-7 s-1.)

A good matlab code that analysis the ROC curve and corresponding AUC value to estimate the sensitive and the currectness of the sample estimate. This code is suitable for variable type and function data.
