小m序列生成程序，可以生成32比特长度的小m序列并具有相对好的自相关特性(m sequence generate)

课程设计中首先采用Ising model的思想建立一个二维的模型，然后利用重要性抽样和Monte Carlo方法及其思想模拟铁磁-顺磁相变过程。计算了顺磁物质的能量平均值Ev、热容Cv、磁化强度M及磁化率X的值，进而研究Ev、Cv、M、X与温度T的变化关系并绘制成Ev-T图、Cv-T图、M-T图、X-T图，得出顺磁物质的内能随着温度的升高先增大而后趋于稳定值；热容Cv、磁化率X随着温度的升高先增大后减小；磁化强度M在转变温度Tc处迅速减小为零，找出铁磁相变的转变温度Tc大约为2.35(First of all, curriculum design idea of the Ising model used to establish a two-dimensional model, the importance of sampling and then use Monte Carlo simulation methods and their idea of ferromagnetic- paramagnetic phase transition process. Paramagnetic material calculated average energy Ev, heat capacity Cv, magnetization M and susceptibility X value, and then study Ev, Cv, M, X and temperature changes in the relationship between T and plotted into Ev-T map, Cv- T diagram, MT map, XT maps drawn paramagnetic material can be increased as the temperature increased and then stabilized value heat capacity Cv, magnetic susceptibility X as the temperature increases after the first minus small magnetization M in the transition temperature Tc decreases rapidly to zero Department to identify ferromagnetic phase transition around the transition temperature Tc for 2.35)

这是一个假期作业，资源很简单，自愿下载，本人自己认真书写的。谢谢(It is a holiday homework, resource is very simple, voluntary download, herself carefully written. thank you)

说明：  1. To design IIR filters in MATLAB to achieve various types of frequency selectivity, e.g.,lowpass, highpass, bandpass, etc 2. To implement the designed IIR filters in different architectural forms (e.g., direct form vssecond-order cascade form) using C6713 DSK 3. To perform real-time testing of the performance of the designed IIR filters.

Program to use your camera as a scanner. Automatically detects the page on the picture. (Description Useful program if you don t have a scanner or need to scan quickly a lot of pages. It detects the page on the picture, make it rectangular, cut the borders and enhance the contrast. Function parameters are the input picture filename and output filename. Some parameters that can be changed are described in the function. Be careful with the flash of the camera, it creates a non-homogeneous luminosity difficult to clean. Required Products Image Processing Toolbox MATLAB release MATLAB 7.5 (R2007b) )
