I want to concatenate horizontally these two tables in order to obtain an array 3262x473. If you want them to be distinct variables in the result, then you do need a concatenation with [] but you'd have to rename one of the duplicate variable name. At the moment, we don't have enough information on what you want to tell you which to use and how to use it. cat and horzcat provide a functional form of that, but the standard MATLAB way is brackets. 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). At the moment, we don't have enough information on what you want to tell you which to use and how to use it. or timetable. Adriano, to horizontally concatenate anything in MATLAB, you would probably just use square brackets, right? returns a 0-by-3 empty array. This really helped me solve the problem thank you. You may receive emails, depending on your. MATLAB has a specific data structure called table, but for your data you are just concatenating matrices. If I do C=[A,B] , it gives me the error "Duplicate table variable name". Vous possdez une version modifie de cet exemple.
