MATLAB: How to put text into an array

arraytext;

Hi all,

I have a big text right now and I wish to put every line as an array… could someone help?

    201403      0.000      8.333       0.00       0.00

So this is one of the lines of my text, and I wish to sort it as an array like

    2014 03 0.000 8.333 0.00 0.00

Can anybody help please?

Thanks!

Hint:

    >> str = '201403      0.000      8.333       0.00       0.00';
    >> cac = textscan( str, '%4f%2f%f%f%f%f', 'CollectOutput', true )
    cac = 
        [1x6 double]
    >> cac{:}
    ans =
       1.0e+03 *
        2.0140    0.0030         0    0.0083         0         0

MATLAB: How to put big text into an array

Though I do not quite understand what you mean by 'sort it with a loop', a good place to start with would be the Import Tool. You should be able to bring in your data into MATLAB and then manipulate it as you please. It also lets you generate code that captures the workflow you followed in the Import Tool and makes it reusable.

MATLAB: Dlmread reading file incorrectly

The data you have shown does not use tab as the delimiter, but uses four space characters.

You could use textscan, which has an option to merge repeated delimiters:

opts = {'HeaderLines',2, 'MultipleDelimsAsOne',true};
fid = fopen('temp.txt','rt');
M = cell2mat(textscan(fid,'%f%f%f',opts{:}));
fclose(fid);

imports this:

>> M
M =
  9.9800e-004  9.9800e-004  6.1593e-012
  9.9800e-004  2.9940e-003  9.8748e-011
  9.9800e-004  4.9900e-003  4.5617e-010
  9.9800e-004  6.9860e-003  1.1994e-009
