csvread reading only column or full matrice in 2015a / b

Hi !

I am currently triing to code something which would import ( or read in this case ) some csv files I have which look like this and which are 1024*1024.

I am working on two computers, one with Matlab 2015a, the other one with 2015b.

When I simply type in Matlab 2015a the code :

 A = csvread ('file.txt')

I get an A matrice which is 1024*1024 ( as expected ). But when I type the same line, for the same file, in the same folder, on Matlab 2015b , I get an A matrice which is 1024*1.

And when I inserted in Matlab 2015a this line of code into a script, I then obtained the 1024*1 matrice ! I must say that I am now completely confused, as I never detailled in the code earlier something about importing only specifics rows/columns or whatever.

Do you have an idea about this issue ?

Thank you very much.

csvread() is for comma separated values; what you show is either space separated or tab separated.

If it is space separated then you can use

A = load('file.txt', '-ascii');

Wonderful ! I see that you are right. i guess that I stayed on the csvread option because it kinda worked out perfectly well when it imported the 1024*1024 matrice.

So your suggestion solves my issue. But do you know why I had this weird behaviour ?

Thank you !
