使用interpolate函数插值法填充缺失值。 data = fillmissing(data, 'linear'); % 使用线性插值法填充缺失值 复制代码 使用delete函数删除包含NaN值的行或列。 data = data(~any(isnan(data), 2), :); % 删除包含NaN值的行 data = data(:, ~any(isnan(data), 1)); % 删除包含NaN值的列 复制代码 使...
You can usemisdatato estimate missing values. This command linearly interpolates missing values to estimate the first model. Then, it uses this model to estimate the missing data as parameters by minimizing the output prediction errors obtained from the reconstructed data. You can specify the model...
I am trying to linearly interpolate a missing value by using values that were measured before and after the missing data. However, I don't want to use the first value measured before and after the missing data. Rather I would like use n values before and after t...
This short video shows how you can take a sparsely sampled sine wave and use interp1 to interpolate the missing data points. Different interpolations such as linear, spline and nearest are all shown. Some people would consider this to be curve fittin

This short video shows how you can take a sparsely sampled sine wave and use interp1 to interpolate the missing data points. Different interpolations such as linear, spline and nearest are all shown. Some people would consider this to be curve fitting to some degree. This is a modal ...
Find or generate the missing data so that each coordinate has an associated vector. If the data sets are unrelated, you need to reconsider how you are trying to interpolate the vector field and ensure that the data is consistent. If you have two separate sets of points—one set for the ...

在Matlab中,可以使用函数ismissing()来检测数据中的缺失值,并使用函数fillmissing()来填充缺失值。此外,还可以使用函数interpolateMissing()来进行插值处理,以逼近缺失值的真实取值。 1.3异常值处理 异常值通常是数据中的异常点或离群点,可能会对分析结果产生不良影响。在Matlab中,可以使用函数isoutlier()来检测数据中的...
