One matrix for different amount of values

Hello,

I would like to have a matrix for the variable time(sec).

Basicallly something like this for ten different testing situations

time =(10,X)

Unfortunately the time for the testings is not fix and therefor I have different testings times:

time =
1 2 3 4 5 6 7 
1 2 3 4 5 
1 2 3 4 5 6 
1 2 3
...

Is it still possible to do it within a matrix?

Or should I sperate them?

Thanks.

In a matrix every row has the same number of columns. In your case a good option is to use a cell array
