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.
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 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.
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.
