How to make a column of cells into array? Each cell in a row when made into an array would a row with different number of columns

Can I also ask, how can I make into arrays a column of cell files?

timeatstayandtripcomp=Scenario1_indvoutputagg(1:r,88); %each row of the cell represents the variable for each ID
timeatstayandtripcomp=cell2mat(timeatstayandtripcomp);

I'd like each row in there to be an array. I've tried cell2mat but get Error using cat; I think it's because the number of columns for each row isn't necessarily the same.

I could maybe do a for loop, but I need to repeat this for many variables, so I'm wondering if there's a more efficient way of doing it

Download Jos's padcat:

and use it like this:

M = padcat(Scenario1_indvoutputagg{1:r,88})

Thanks!

Is there a coding way of doing this though?

The reason I ask is because I need to run the script on a computing network, and I don't know if I'll be able to download it onto that network.

"Is there a coding way of doing this though?"

Sure: measure the sizes of the vectors, preallocate an output array to fit the largest vector, then use a loop to assign each of the vectors to that array. It will be quite efficient and is trivial to implement.

Thanks very much!
