Data Types: double | single filter(b,a,x,zi,dim):dim是指定维度,如果x是一个矩阵,那么如果dim为1(默认值),那么就把对矩阵的每个列进行滤波,如果dim为2,则对矩阵的行进行滤波。 Filter Data in Sections Use initial and final conditions for filter delays to filter data in sections, especially if m...
Filters are data processing techniques that can smooth out high-frequency fluctuations in data or remove periodic trends of a specific frequency from data. In MATLAB®, thefilterfunction filters a vector of dataxaccording to the following difference equation, which describes a tapped delay-line fil...

Filter Data Filter Difference Equation(滤波器差分方程) 滤波器是一种数据处理技术,可以消除数据中的高频波动或从数据中去除特定频率的周期性趋势。 在MATLAB®中,滤波器功能根据以下差分方程过滤数据x的向量,该差分方程描述了抽头延迟线滤波器。 在该等式中,a和b是滤波器系数的矢量,Na是反馈滤波器阶数,Nb是前...
【摘要】 【 MATLAB 】filter 函数介绍(一维数字滤波器) 在上篇博文中,里面有一个例子,就是过滤部分中的数据,这个部分中的数据的意思是如果有一个向量需要过滤,我们可以把它分为几段,然后分段过滤。 关于这个问题,使用语法: [y,zf] = filter(___) 赋值符号左边的部分有一个y是过滤后的数据,那至于zf到底是...
I am new to MATLAB, I want to filter some data on the image I send attached, I tried to use smooth funciton but I think it only works with plot and I want to be able to use it with the scatter function. I know I can erase this dots manually with the brush/select data directly...
