isspace finds wrong spaces in ascii file

Hi.

I am using the function below to create separations in my line file. It used to work just fine, however for some reason it now sets the spaces at non-space places (e.g., 75666 83929 92920---created '5666' '3929' '2920').

[rows] = size( line );

    for R = 1:rows
        sep {R,1} = find( isspace ( line{R} ) );

    end

Any advise would be highly appreciated.

Best Regards Dana

I do not see how the posted code converts "75666 83929 92920" to '5666' '3929' '2920'.

After "rows = size(line)" the variable "rows" is a vector. Therefore "for R=1:rows" does not what you expect most likely.

Please explain the input exactly (what is "line"?) and the wanted output.

If you're trying to split that sequence:

% example input:
line = {'75666 83929 92920'
        '75466 39293 92320 32424'};

tks = regexp(line,'\d+','match');
% This concatenation will work if the number of sequence is equal per each row 
tks = cat(1,tks{:});

Thanks Oleg.

I am not super great with codes so excuse the question if it strikes you as basic.

What would this do exactly? I was thinking perhaps I could just add somehow an extra space in front of my number strings to let the function find another space.

Any idea how I could do that?

[Oleg Komarov]

The code I posted takes a cell-array of strings and processes string by string (contained in each cell) by separating the numerical sequences whenever a space occurs.

Lets say you have:

line = {'75666 83929 92920'}

You will get:

tks = {'75666' '83929' '92920'};
