一个强大的工具分析 寻找 逆转录(逆转录)跟随由聚合酶链反应，该程序定量分析信使核糖核酸。定量表达基因水平，特别是能为低级的丰富信使核糖核酸提供分析工具。(Reverse transcription(RT) followed by PCR is a powerful tool for the detection and quantification of mRNA. It is the most sensitive method for the detection and quantification of gene expression levels, in particular for low abundance mRNA. The relative quantification is based on the expression ratio of a target gene versus a reference gene. Some mathematical models have already been developed to calculate the relative expression ratios, with or without efficiency correction. Normally the PCR efficiency is set at 2 (the max possible value) for the reference and target gene, but a difference in PCR efficiency of 0.03 between the target and reference gene, the falsely calculated difference in expression ratio is 46 in case of Et<Er and 209 in the case of Et>Er. The difference will increase dramatically by higher efficiency differences: i.e. DE=0.05 (27 and 338 ) and DE=0.1 (7.2 and 1083 ) This function computes the efficiency of PCR reaction and is based on my function MYREGR)

该程序利用空时二维自适应处理的原理，采用最优处理器的方法，对杂波矩阵进行处理，并能够绘制出二维杂波功率谱图，功率谱亮度图，特征谱图，二维频响图，以及最优化比较图(the code can draw 5 pictures of the Clutter matrix,including :Clutter power spectrum, power spectral brightness diagram, characteristic spectra, two-dimensional frequency response graph and the optimal comparison chart )

IS95中的数据流伪随机序列的产生。用matlab中randn实现(IS95 data streams to be pseudo-random sequence generation. Achieved using randn in matlab)

说明：  利用FFT对原信号进行变换，然后在频域进行处理，再使用IFFT进行反变换，达到滤波的目的。(use FFT and IFFT to filter)

MATLAB是解释型语言,运行速度比较慢.本文探讨提高MATLAB程序运行效率的若干手段.(MATLAB is an interpreted language, run more slowly. Article explores improve the operating efficiency of the program MATLAB several means.)

利用STFT可以估计信号在每片短时窗内的频率得到信号的瞬时频率，该曲线由一组时间和频率相对应的点组成，反映了信号频率随时间的变化。(Using STFT can estimate the frequency of the signal in every piece of short-time window get signal instantaneous frequency, the curve consists of a set of time and frequency of corresponding points, reflects the signal frequency changes over time. )

教程 全程掌握。对于初学者来说是非常好的工具。(Master the whole course. For beginners it is a very good tool.)
