能够分辨出一幅图像中的矩形和圆形，并做以标记。(Able to distinguish an image of the rectangular and circular, and do the marking.)

FT2 M-file for ft2.fig FT2, by itself, creates a new FT2 or raises the existingsingleton.

说明：  上传的是Levenberg-Marquardt算法的Matlab程序(Upload is the Levenberg-Marquardt algorithm in Matlab)

Total gradient method extremum If using MATLAB is not difficult, but with C + + is not very easy.(Total gradient method extremum If using MATLAB is not difficult, but with C++ is not very easy.)

涉及机械土木工程的常用刚架结构的计算，给出计算实例及matlab源程序，是提高工程设计方法的有效手段(Mechanical Engineering involves the calculation of a common frame structure, a numerical example and the matlab source code is to improve the engineering design method of an effective means of)

碰磨相关的非线性输出频率响应的处理程序，MATLAB应用，应该对做这方面研究的有用处。(Rubbing nonlinear output frequency response associated with the process, MATLAB applications should do research in this area useful.)

it is an implementation of the algorhytm for the identification R peaks based on Pan-Tompkin

经验模态分解方法简称EMD方法。该方法从本质上讲是对一个信号进行平稳化处理，其结果是将信号中真实存在的不同尺度波动或趋势逐级分解开来，产生一系列具有不同特征尺度的数据序列。(Empirical mode decomposition method is referred to as the EMD method. This method is in essence a signal smoothing processing, the result is the real signal different scales swings or trends gradual decomposition open, resulting in a series of a data sequence having a different characteristic scale.)

支持向量机代码，和Matlab上自带的代码不一样啊(Support vector machine code)

说明：  对信号类型的说明，并画出其相应的波形，求出信号的功率和能量。(Description of the type of signal, and draw the corresponding waveform, find the power and energy of the signal.)
