A is a 19-by-3 table.
Since ordinal categorical arrays have a mathematical ordering for their categories, you can perform
element-wise comparisons of them with relational operations, such as greater than and less than.
Create a subtable, T2, of the gender, age, height, and weight of all patients who assessed their health
status as poor or fair.
First, define the subset of rows to include in table T2.
rows = T.SelfAssessedHealthStatus<='Fair';
Then, define the subset of variables to include in table T2.
vars = {'Gender','Age','Height','Weight'};
Use parentheses to create the subtable T2.
T2 = T(rows,vars)
