Matlab Desktop 2023a, tables have new feature that automatically displays summary statistics for each column in the table. How do I access and save stats from within matlab?

Hello I recently downloaded and installed the 2023a desktop version of matlab and its accompanying dark mode. I noticed while creating a table that useful summary statistics were provided in each column, such as calculating the max, min, and stdev.

In other cases it would calculate the numer of times a unique string showed up.

I'm wondering is there a way to directly acess this data and save it to a variable from within matlab? I've provided a picture of what I mean below (see the top of the table)

Hi Michael,

It is my understanding that you want to store the summary of a table to a variable.

Suppose you have the following table:

patients=5×6 table
LastName     Age    Smoker    Height    Weight BloodPressure
"Sanchez"    38     true        71       176       124     93  
"Johnson"    43     false       69       163       109     77  
"Zhang"      38     true        64       131       125     83  
"Diaz"       40     false       67       133       117     75  
"Brown"      49     true        64       119       122     80  

You can define a struct:

tableSummary = summary(patients)

You can access the stats of the table using the "tableSummary" variable.

For example, To get the minimum value in the "Age" column:

s.Age.Min

To learn more about table summary, you can refer to the below MathWorks documentation.

I hope this information helps!
