### Improve Workspace Browser Performance during Statistical Calculations

For each variable or object, the Workspace browser displays
statistics such as the **Min**, **Max**,
and **Mean** calculations, when relevant. MATLAB^{®} performs
these calculations using the `min`

, `max`

,
and `mean`

functions, and updates the results automatically.

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 to change the value
of the maximum array size for which you want the Workspace browser
to perform 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, 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
some other statistics will appear as `NaN`

. However, **Mode**,
for example, shows 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** and **Max**. **Var**,
however, is still appears as `NaN`

.
