Before MATLAB Version 9.4 (R2018a), MATLAB used aseparatestorage representation. The data is stored as two vectors of double-precision numbers—one contains the real data and one contains the imaginary data. The
Data Types:single|double Output Arguments collapse all Trimmed mean values, returned as a scalar, vector, matrix, or multidimensional array. Tips The trimmed mean is a robust estimate of the location of a data sample. If the data contains outliers, then the trimmed mean represents the center ...

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 attenuates approximately 100*τ percent of the energy of the input data. ...

The upper and lower bandwidths of a matrix are measured by finding the last diagonal (above or below the main diagonal, respectively) that contains nonzero values. That is, for a matrix A with elements Aij: The upper bandwidth B1 is the smallest number such that Aij=0 whenever j−i>B...
