How to extract a subtable by rownames?

Hi,

I have a table of 10 columns and one column represent last names. I would like to extract all the rows that belong to one last name. How to do that? Thanks in advance.

Modifying the example on this documentation page a bit:

% Make a patients table
load patients
patients = table(Age,Gender,Height,Weight,Smoker,...
  'RowNames',LastName);

% Give each patient a random first name 
bloggers = {'Cleve'; 'Loren'; 'Guy'; 'Steve'; 'Stuart'; 'Hans'};
n = numel(bloggers);
p = size(patients, 1);
patients.FirstName = bloggers (randi([1 n], p, 1));

% Retrieve all patients named Steve using logical indexing
patientsNamedSteve = patients(strcmp(patients.FirstName, 'Steve'), :);

% There shouldn't be any patients named Aaron; check using logical indexing
patientsNamedAaron = patients(strcmp(patients.FirstName, 'Aaron'), :)
isempty(patientsNamedAaron) % true
