When the window size for the smoothing method is not specified,smoothdatacomputes a default window size based on a heuristic. For a smoothing factor τ, the heuristic estimates a moving average window size that
You can also smooth data by using the MATLAB® smoothdata function. With the exception of GPU array support, smoothdata includes all the functionality of the smooth function and has some advantages. Unlike smooth, the smoothdata function supports: Matrices, tables, and timetables Moving median ...

This MATLAB function smooths the trajectory data in the input Trajectory object trajectory using a Savitzky-Golay filter.
The Smooth Data task lets you interactively smooth noisy data. The task automatically generates MATLAB® code for your live script. Using this task, you can: Customize the method for smoothing data in a workspace variable. Adjust parameters to generate less or more smoothing. Automatically visuali...
B = smoothdata(___,method) B = smoothdata(___,method,window) B = smoothdata(___,nanflag) B = smoothdata(___,Name,Value) [B,window] = smoothdata(___) How does Smooth works in Matlab? In matlab smooth ‘smooth’ statement is use for smooth response data. The ‘smoothdata’ ...
Open in MATLAB Online hello FYI a demo code for various methods of data smoothing that does not require CFT Fs = 1000; samples = 1000; dt = 1/Fs; t = (0:samples-1)*dt; y = square(2*pi*3*t) + 0.1*randn(size(t));
Data Types:single|double|int8|int16|int32|int64|uint8|uint16|uint32|uint64|logical Smoothing method, specified as one of these filters: "box"— Weighted moving average over each window ofV "gaussian"— Gaussian-weighted moving average over each window ofV ...
首先将数据文件从当前文件夹导入到MATLAB中,可以使用xlsread等函数导入xls文件可以参考下面这篇文章 灵魂歌手水云天:MATLAB中文件的操作 此处以网上一组数据——某日某城市股市日收盘价来学习smoothdata函数,导入之后的数据为一个向量price,绘制该数据的散点图如下: 函数smoothdata共支持八种平滑方法,类似上面的smooth函数...
the other data.Which is the best way to smooth them.Both in 2d and 1d matrix.I provide some examples to be more clear:It's impossible to say what the best method is without a model of spike formation and a function that quantifies the cost of residual errors in the smoothed data. ...
