MATLAB: How to read a list of strings in a txt file

Question

Dear All,

I need to read a txt file which contains a list of names with different lengths. Here is my txt file:

mynames:

OAKFIELD

5556_T

ROLLINS

……

I need to read those names to store them in a string array MyNames. MyNames should be like below:

MyNames = [

'OAKFIELD'

'5556_T'

'ROLLINS'

……

];

Here is my code:

fid = fopen(FileName, 'r');

if fid < 0, error('Cannot open file'); end

while KKK < 30000 % Infinite loop

s = fgets(fid);

if ischar(s)

MyNames = [MyNames; s];

else % End of file:

break;

end

end

But what I got is Not correct. MyNames is an array having 10 coulmns and shows as

'CHSTRSVC←↵'

'5556_T'←↵'

'ROLLINS←↵'

…

Answer 1

Unless I am missing something, ‘KKK’ is never incremented inside the while loop, so it will in fact be infinite.

If you are actually using ‘KKK’ as a counter (and therefore incrementing it), this could work:

MyNames{KKK} = s;

That creates a cell array, and while that can create additional steps required to recover its contents later, it could be an effective approach.

A better approach could be readtable. The first variable would be the names, and you could simply ignore the others.
