Accelerating the pace of engineering and science. different names. 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. Concatenate two matrices horizontally. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. horzcat is equivalent to using square brackets to horizontally concatenate or append arrays. more information, see Tall Arrays. more information, see Run MATLAB Functions in Thread-Based Environment. Hello, I have a code that uploads excel data into UItable. MATLAB has a specific data structure called table, but for your data you are just concatenating matrices. My weird mental block is not being able to immediately see my own typos which happens frequently to me. Similarly, all timetable inputs must have the same row times and all columns must have different names. {''potato'' } {'200'} {''g'' } {'738126'} {''Use By'' } {'0' } I want to concatenate the rows of the table however, some of the output are special charaters.
