matlabmean时有nan 文心快码BaiduComate 当在MATLAB中使用mean函数计算平均值时遇到NaN值,这通常会导致整个计算结果也变成NaN。为了处理这种情况,你可以遵循以下步骤来确保计算平均值时忽略NaN值: 1. 确认数据中NaN值的存在 在尝试计算平均值之前,首先确认你的数据集中是否存在NaN值。可以使用isnan函数来检测数据中的...
nanmean无法识别matlab，是因为格式无法匹配，可以通过插件识别matlab，首先先下载一个插件即可。
R2020b:nanmeanis not recommended nanmeanis not recommended. Use the MATLAB functionmeaninstead. There are no plans to removenanmean. To update your code, change instances of the function namenanmeantomean. Then specify the'omitnan'option for thenanflaginput argument. ...
example m= trimmean(X,percent)returns the mean of values ofX, computed after removing the outliers ofX. For example, ifXis a vector that hasnvalues,mis the mean ofXexcluding the highest and lowestkdata values, wherek = n*(percent/100)/2. ...
We can see that the vector contains some missing values i.e. nan. The data shows the variation in a certain variable for 40 days i.e. there are 40 24 hours in the vector. How could I replace the missing values with the average for that particular 24 hour, in addition, if 24 ...

knanmean(X,[dim]) returns the average of matrix X on dimension dim, treating NaNs as missing values. Contrarly to nanmean, works on n-dimensions matrices Cite As Alexandre Reynaud (2024). knanmean (https://www.mathworks.com/matlabcentral/fileexchange/26565-knanmean), MATLAB Central File...
Open in MATLAB Online Download For vectors, Y = RUNMEAN(X,M) computes a running mean (also known as moving average) on the elements of the vector X. It uses a window of 2*M+1 datapoints. M an positive integer defining (half) the size of the window. In pseudo code: ...
