Changes to DimensionNames Property in R2016b

The table data type is suitable for collecting column-oriented, heterogeneous data in a

single container. Tables also contain metadata properties such as variable names, row

names, dimension names, descriptions, and variable units. Starting in R2016b, you can

use the dimension names to access table data and metadata using dot subscripting. To

support that, the dimension names must satisfy the same requirements as the variable

names. For backwards compatibility, tables enforce those restrictions by automatically

modifying dimension names when needed.

Create a table that has row names and variable names.

Number = [8; 21; 13; 20; 11];

Name = {'Van Buren'; 'Arthur'; 'Fillmore'; 'Garfield'; 'Polk'};

Party = categorical({'Democratic'; 'Republican'; 'Whig'; 'Republican'; 'Republican'});

T = table(Number,Party,'RowNames',Name)

T =

Number Party

______ __________

Van Buren 8 Democratic

Arthur 21 Republican

Fillmore 13 Whig

Garfield 20 Republican

Polk 11 Republican

Display its properties, including the dimension names. The default values of the

dimension names are 'Row' and 'Variables'.
