It would be much easier for us to help if you uploaded
- your data file
- your code (instead of an image of your code)
However, it seems all you need is to take the transpose, and then convert to a vector. I think this will do what you want, but I can't be sure because I can't test it against your data:
T = csvread('matlab test.csv');
The reason for doing the transpose first is that when the last line of code converts to a vector, it is going to read down each column in turn (because that is how the array is stored internally).
FYI, another handy command for doing such manipulations is reshape.
