基于matlab简单计算器，和我们平时用的普通计算器一样(Matlab prepared easy to use calculator)

说明：  EEGLAB学习资料，对出学习和有很大的帮助，希望对你有用(EEGLAB learning materials, on the study and a great help, I hope useful to you)

设计一个数字滤波器，在频率低于 的范围内，低通幅度特性为常数，并且不低于0.75dB。在频率 和 之间，阻带衰减至少为20dB。 (1)试求满足这些条件的最低阶Butterworth滤波器。(Design a digital filter, in the range of frequencies below the low-pass amplitude characteristic is constant, and not less than 0.75dB. Between the frequency and stop-band attenuation of at least 20dB. (1) Determine the lowest-order Butterworth filter to meet these conditions.)

Welch法：Welch法对Bartlett法进行了两方面的修正：一是选择适当的窗函数w(n)，并在周期图计算前直接加进去，加窗的优点是无论什么样的窗函数均可使谱估计非负。二是在分段时,可使各段之间有重叠，这样会使方差减小。(Welch method: Welch method of Bartlett method amendments in two respects: First, select the appropriate window function w (n), and in the cycle before CALPHAD directly incorporated, plus the advantage of the window, no matter what kind of window function can be so spectral estimation of non-negative. Second, when in subparagraph can overlap between paragraphs, this would reduce the variance.)

MATLAB常用的例子，这里举了100个常用的，目录已经单独传上，这是一部分例题!(MATLAB common examples cited here of the 100 commonly used, the directory has a separate mass, which is part of sample questions!)

剪切图片，有利于初学者，希望能够帮助有些人(cut picture)

q学习算法，在MATLAB中实现，本人已运行成功，希望有帮助(q learning algorithm implemented in MATLAB, I have run successfully, the hope of helping)

说明：  小波阈值去噪。对图像加噪，并进行小波1到4层分解去噪，给出信噪比走势图(Wavelet thresholding. Increase the image noise, and 1 to 4 layers of wavelet decomposition denoising, signal to noise ratio charts are given)

以八个锚链受力平衡、力矩平衡为对象，使用Vb调用matlab进行线性最小化计算函数，matlab调用的函数写在m文件中。(To eight anchor the balance of power, torque balance for the object, using Vb call matlab linear function minimization calculations, matlab function calls written in the m file.)

这是一个鼠标程序，按Ctrl键同时按鼠标左键画圆，按shift同时按鼠标左键画矩形(This is a mouse program, press the Ctrl key while pressing the left mouse button circle, press shift while pressing the left mouse button draw a rectangle...)
