You just need to concatenate your tables vertically instead of horizontally: S = [s1; s2; s3]; % Or in functional form S = vertcat (s1, s2, s3); Note that this only works if all the tables have the same number of variables (i.e. 3 Comments Show 2 older comments Douglas Novaes on 12 Sep 2022 Perfect! You need to say exactly what you started from and what you did. For instance I tried to concatenate two tables A (size 32x4) and B (size 32x50) and I ended up with AB . Here is an example: Theme Copy myTable1 = array2table (eye (3)); myTable1.Properties.VariableNames = ["One","Two","Three"]; https://www.mathworks.com/help/matlab/matlab_prog/valid-combinations-of-unlike-classes.html, TYPE | character | integer | single | double | logical, character | character | character | character | character | invalid, So when you [] together a character vector and a numeric value, the result is a character vector. {'chicken breast 200 g 738113 Use By 0 ' }
Fixed, I seem to have a weird mental block with plural in english. I have two tables 3262x218 (let's call it A) and 3262x255 (let's call it B) . It helps us in combining data present in different cells. A and B have compatible sizes (the lengths of the {''pasta' 250 'g' 738160 'Best Before' 3 ' }
You can concatenate valid combinations of different types. C = horzcat (A,B) concatenates B horizontally to the end of A when A and B have compatible sizes (the lengths of the dimensions match except in the second dimension). If you are looking at joining the table, then there are different types of joins: left outer join, right outer join, full outer join, inner join, and plain join.
