神经网络修改BP辨识算法，用于辨识复杂的非线性系统，相对传统BP算法，具有计算快等优点(Modify BP neural network recognition algorithm for identification of complex nonlinear system, compared to the traditional BP algorithm has the advantages of quick calculation)

二维的克吕金插值，适用于地学类等领域，使用方便(Two-dimensional krig interpolation, applied geosciences)

Jadi, analisis Kurva Tegangan dan studi tentang motor sinkron menggunakan MATLAB m-file adalah pilihan yang baik di lingkungan industri.

利用Mindlin解，求解弹性半无限体内作用水平集中力引起的任一点的位移。(The soil movements of Mindlin solution introduced by a single horizontal force in semi-inifite plate.)

自适应多速率编码器标准代码，编码端。可将wav文件编码生成amr格式的文件。这种格式的文件可根据信道质量，自动调节编码速率，故称之为自适应。(adaptive multi-rate coding standards for code-coding. Wav documents can be generated amr coding format documents. This format of the document is available according to the channel quality, automatic adjustment coding rate, but it is called adaptive.)

this is matlab code for noise estimation

In this section, the PAPR performance of the proposed algorithms is shown. To evaluate the PAPR performance, the CCDF is employed. The specification detail of simulation parameters is given in TABLE I. In Fig. 5 is shown the PAPR with a PTS method (U = 8) and conventional PTS (U = 4) are improved 4.3 dB and 2.6 dB from ordinary MIMO-OFDM signal when CCDF = 10− 4 respectively and Fig. 6 is shown the PAPR with an optimal PTS method in case of 128 subcarriers.
