Display Statistics in the Workspace Browser
For each variable or object, the Workspace browser can display statistics such as the
Min, Max, and Mean,
when relevant. MATLAB® performs these calculations using the min,
max, and mean functions, and updates the
results automatically.
To display statistics, on the Workspace browser title bar, click 
, and then select Choose
Columns. Select the statistics you want MATLAB to calculate. In MATLAB
Online™, to select which columns to display, right-click a column name in the
Workspace browser and select or clear the desired column names.
Improve Workspace Browser Performance During Statistical Calculations
If you show statistical columns in the Workspace browser, and you work with very large arrays, you might experience performance issues when the data changes as MATLAB updates the statistical results. To improve performance, consider one or both of the following:
Show only the statistics of interest to you.
On the Workspace browser title bar, click
, and then select Choose
Columns. Clear the statistics that you do not want
MATLAB to calculate. In MATLAB
Online, to change which statistics display, right-click a column name
in the Workspace browser and clear the statistics that you do not want
MATLAB to calculate.Exclude large arrays from statistical calculations.
On the Home tab, in the Environment section, click
Preferences. Select MATLAB > Workspace, and then use the arrow buttons under Statistical
calculations to change the maximum array size for which the
Workspace browser performs statistical calculations. Any variable exceeding
the maximum array size reports <Too many elements>in Workspace browser statistics columns instead of statistical results.Changing Workspace preferences is not supported in MATLAB Online.
Include or Exclude NaN Values in Statistical Calculations
If your data includes NaNs (Not-a-Number values), you can
specify that the Workspace browser statistical calculations consider or ignore the
NaNs. On the Home tab, in the
Environment section, click
Preferences. Select MATLAB > Workspace, and then select one of the following:
Use NaNs when calculating statistics
If a variable includes a
NaN, and you select this option, the values for Min, Max, Var, and several other statistics appear asNaN. However, Mode and several other statistics show a numeric result.Ignore NaNs whenever possible
If a variable includes a
NaN, and you select this option, numeric results appear for most statistics including Min, Max, and Mode. However, Var still appears asNaN.
Changing Workspace preferences is not supported in MATLAB Online.
