Convert data file to char array

Question

I have a file(res.txt) that looks like this:

a
na
na
a
a
a
na

I need to read this into a matrix and import into workspace. using textscan makes it a cell array. hence, a(2)=n not na . How do I import this file into a 1D matrix?

Try:

fid = fopen('file.txt','rt')
C = textscan(fid, '%s', 'Delimiter',''); C = C{1};
fclose(fid);

Now each element of the cell array C{i} contains one line.

If you want an actual character matrix (padded with spaces of course), convert the cell array using:

arr = char(C);

Now each line is: arr(i,:) (might want to use deblank on that)

What is C? a cell matrix or a character matrix?

@MaxSteel: C is a cell array of strings of size 7-by-1. arr is a character matrix of size 7-by-2 (padded with spaces since MATLAB matrices cannot be jagged)
