Hello,
I have a table that needs to be concatenated, with a new table (T_nm) I'm trying to create. The table should have rows equal to the length of the vector ("obs") and have two columns with the variable names "subject" and "prov", respectively.
The column, "subject", should be filled with, the input corresponding to the variable, "n" and the "prov"-column filled with "m". These variables will change for different tables, but always be in the form of text/character.
I have created an empty table;
T_nm = table('Size', [numel(obs) 2], 'VariableTypes', ["string", "string"], 'VariableNames', {'subject', 'prov'})
However, I'm not successfull filling the column rows with "n" and "m", respectively.
Any advice is much appreciated!

You can use the “repmat” as shown in the code below.
% Define the variables
n = 'value of n';
m = 'value of m';
% Replace with your own vector
obs = [1, 2, 3];
% Create a new table
T_nm = table(repmat({n}, length(obs), 1), repmat({m}, length(obs), 1), 'VariableNames', {'subject', 'prov'});
You can go through the link given below to understand more about “repmat”.
Repeat copies of array - MATLAB repmat (mathworks.com)
Hope this helps!
