how to renamne column names using totable() in matlab

To rename column names in MATLAB using the table function, you can use the setvartype method along with the array2table function. Here's an example:

main.m
% Create a sample table
data = rand(5, 3);
tableData = array2table(data, 'VariableNames', {'Column1', 'Column2', 'Column3'});

% Rename column names using the setvartype method
newColumnNames = {'NewName1', 'NewName2', 'NewName3'};
tableData.Properties.VariableNames = newColumnNames;

% Display the table with new column names
disp(tableData);
345 chars
11 lines

In the example above, we first create a sample table called tableData with three columns named 'Column1', 'Column2', and 'Column3'. Then, we assign a new cell array of column names to the Properties.VariableNames property of the table, using the setvartype method. Finally, we display the updated table using the disp function.

Please note that the setvartype method is used to change the data type of table variables, but it can also be used to rename the column names as shown in the example.
