how to set column names of a matri in matlab

To set column names of a matrix in MATLAB, you can use the table function. First, create your matrix and then convert it into a table. You can set the names of the columns using the Properties.VariableNames property. Here's an example:

main.m
% create a matrix
mat = [1 2 3; 4 5 6; 7 8 9];

% convert matrix to table and set column names
t = array2table(mat, 'VariableNames', {'col1', 'col2', 'col3'});
160 chars
6 lines

In this example, the variable t will be a table with the same values as mat but with column names set to col1, col2, and col3.
