how to iterate over table variable namers in matlab

Assuming we have a table T in matlab and we want to iterate over its variable names. We can use the varnames function to get the variable names and then iterate over them using a for loop. Here's an example:


main.m
% create a sample table
T = table(rand(3,1), rand(3,1), rand(3,1), 'VariableNames', {'Col1', 'Col2', 'Col3'});

% get variable names
varNames = T.Properties.VariableNames;

% iterate over variable names and print them
for i=1:length(varNames)
    fprintf('Variable name: %s\n', varNames{i});
end
296 chars
11 lines

This will print the variable names of the table T:


main.m
Variable name: Col1
Variable name: Col2
Variable name: Col3
60 chars
4 lines

We can then use the variable names to access the table variables within the for loop.
