MATLAB: Importdata not importing as a cell array and instead as a column vector

Question

Hi,

I have this input file as a .txt here

2 
0.0 1.0 6.283185307 
0.0 -1.0 -6.283185307

But when I use importdata, it gives me a line vector as stated:

data =
    2.0000
         0
    1.0000
    6.2832
         0
   -1.0000
   -6.2832

I reckon it is due to the first line of the .txt file being a single integer. I can't change the contents of the .txt file.

Any idea how to fix this?

You can use textscan function to read data from an open text file into a cell array.

f=fopen(‘a.txt’);

data=textscan(f,'%f%f%f',2)

Hope this helps!
