How to store value in the table using looping

1 view (last 30 days)
Hi,
I want to store data in a table using looping. I am trying to store all the value of each iteration in the table but it can only store the values of the last iteration. The coding below is what I tried.
for n = 1:3
Table.Data_A = DataA;
Table.Data_B = DataB;
Table.Data_C = DataC;
Table(n,;) = Table;
end
I will appreciate if someone can help me.
Thank you.

hello, below you can find an example on how to store data in a table in a loop
numLoop = 10; % indicate the number of loops...
numCol = 3; % indicate the number of columns for the table...
% generate some random data
DataA = 1:numLoop;
DataB = rand(numLoop,1);
DataC = ["A","B","C","D","E","F","G","H","I","J"];
% allocate the table
varTypes = ["double","double","string"]; % data type for each column
varNames = ["DataA","DataB","DataC"]; % variable name for each column
MyTable = table('Size',[numLoop numCol],'VariableTypes',varTypes,'VariableNames',varNames);
% perfom the loop
for n = 1:numLoop
% store data in the table
MyTable(n,:) = {DataA(n), DataB(n), DataC(n)};
end
% display the result
MyTable

Edit: next to the orginal example, i also added modified the code with the later added example data and script, see attachment
@Yew Jen Chong: the code is to slow to run here, however below you can find the print screens of the result run locally (the code is in attachement)
and the remainder of the table...
