By default, smoothdata chooses a best-guess window size for the method depending on the data. smoothdata2 determines the moving window size from the entries in A. Remove unwanted spikes, trends, and outliers from a signal. S = smoothdata2(A) smooths entries of A using a moving average. También puede suavizar datos usando la función smoothdata de MATLAB ®. imgaussfilt(A, 'FilterSize',3); Other option can be to use fspecial function. Show -2 older comments Hide -2 When using a loop to apply the smoothdata function on each column. Unlike smooth, the smoothdata function supports: Matrices, tables, and timetables. These are very similar codes, doing similar things. If we store each new window size in a vector, we would observe that each column outputs a different window size. It can work on multidimensional arrays. The ‘smooth’ statement isuse for smooth response data. Smoothdata is a little more sophisticated, with more options, as you might expect, since it was introduced many years later.
