how to store the matrix in a single table after every iteration

suppose i have a matrix which size is always same but value does not same it will be change after every iteration for i=1:2 matrix result after iteration 1

A         B 
1.21      21.32
21.32     32.21
89.11     32.87

matrix result after iteration 2

A         B
21.32       43.21
43.54        78.32
77.23         99.1

end now i wish to add new matrix in the next column of table when new iteration will be run. all array values are in the table after iteration over.

A         B           A        B
1.21      21.32      21.32     43.21
21.32     32.21      43.54      78.32
89.11     32.87      77.23      99.1

have a look at this inbuild function:

You can't have duplicate variable names (column headers) in a table, so your desired output is not possible.

If you use different column names, then joining two tables is trivial:

t1 = array2table([1.21 21.32; 21.32 32.21; 89.11 32.87], 'VariableNames', {'A1', 'B1'});
t2 = array2table([21.32 43.21; 43.54 78.32; 77.23 99.1], 'VariableNames', {'A2', 'B2'});
tmerged = [t1 t2]

You could generate the variable names for each loop with:

varnames = cellfun(@(prefix) sprintf('%s%d', prefix, i), {'A', 'B'}, 'UniformOutput', false);

I'm not sure it's a good idea, though. Why not concatenate the rows instead of the columns?
