Open in MATLAB Online What sizes do the 4D and 2D arrays have? What do you actually mean by "concatenation": is your goal to do something with the contents of each cell of the 4D array and the contents of the 2D array? Or are you actually wanting to concatenate the arrays t...

I have files namedT0.txt, T3.txt, T6.txt, ..., T600.txt, each is single column vector with 270 real numbers. I want to read these in one go, and concatenate into one single column array. I can do this one at a time but it takes a very long time!
You can't do that. A table has to be rectangular and each column must be the same data type. You can add 0's in columns 8 and 9 like you suggested but that's the only way. Or you can use a cell array instead of a table and just have the columns 8 and 9 be empty/null.
I'd put them into a structure. You can attach each image variable to the structure as a new field.
