You can specify the type of variable with the vartype function. However, you might want to apply a function only to variables of a particular type. varfun is particularly useful for applying a function and returning the results in another table. You also can apply a function to every table variable, using the varfun function. totalCustomers = sum(T.Customers, 'omitnan') For example, calculate the total number of customers affected by power outages using the sum function, omitting any NaN values that might be in T.Customers. One way is to use dot notation to refer to table variables by name and perform calculations. Once data is in a table, you can perform calculations on different table variables. Perform Calculation on Each Numeric Variable T has two categorical variables (specified with %C), two datetime variables ( %D) and two numeric variables ( %f). Since I want to specify the data types of the table variables, I use the Format name-value pair argument.

Region OutageTime Loss Customers RestorationTime Cause To display the first five rows, use table indexing. The file outages.csv contains simulated data for electric power outages over a period of 12 years in the United States. I'm going to use readtable to read data from a sample file that ships with MATLAB. You can create a table using the table function, the Import Tool, or the readtable function. Today I will show several different ways to apply functions to groups in tables.įirst, let's create a table. And you can specify groups within table variables, to perform calculations on those groups. You can access table data by row, by variable, or by variable name.

The variables in a table can have different data types, but must have the same number of rows. Tables are convenient containers for column-oriented data. Use Groups in Multiple Calculations and Tabulate Results.Multiple Variables as Input Arguments to Function.Perform Calculation on Groups in Numeric Variables.Perform Calculation on Each Numeric Variable.
