说明：  基于Matlab GUI的FIR滤波器 实际中，一般调用MATLAB信号处理工具箱函数remezord来计算等波纹滤波器阶数N和加权函数W(ω)，调用函数remez可进行等波纹滤波器的设计，直接求出滤波器系数。函数remezord中的数组fedge为通带和阻带边界频率，数组mval是两个边界处的幅值，而数组dev是通带和阻带的波动，fs是采样频率单位为Hz。(FIR filter based on matlab gui. In practice, the MATLAB signal processing toolbox function remezord is generally called to calculate the order N of the equiripple filter and the weighting function W . The call function remez can be used to design the equiripple filter and directly calculate the filter coefficients. The array fedge in the function remezord is the pass-band and stop-band boundary frequencies, the array mval is the amplitude at the two boundaries, the array dev is the fluctuation of the pass-band and stop-band, and fs is the sampling frequency unit in Hz.)

erilyAlertDialog 是由Herily[虚拟名]研究android对话框源码后的结晶，继承自AlertDialog并根据需要重写了部分代码，使其能满足自己所需要的风格的对话框。你可以像使用AlertDialog一样的使用HerilyAlertDialog。你也可以直接使用HerilyAlertDialog来直接替换已有项目中的AlertDialog而不需要做任何修改。 2.如果你想更换对话框风格，你可以替换掉drawable-hidp中对应的.png图片资源即可。 3.建议配置成双选择形式来使用(通过配置文件或者某一个定向变来空控制到底使用哪一种对话框)(Erily Alert Dialog is the crystallization of the Android dialog source code studied by Herily [virtual name]. It inherits from Alert Dialog and rewrites part of the code according to the need to make it meet the style of dialog box it needs. You can use HerilyAlert Dialog as you would use Alert Dialog. You can also use HerilyAlert Dialog directly to replace Alert Dialog in existing projects without any modifications. 2. If you want to change the dialog style, you can replace the corresponding. PNG image resources in drawable-hidp. 3. It is recommended to configure the dialog box in a double-choice format (to control which dialog box to use by configuring a file or a directional variable))
