if your textfile has delimited characters (i.e. in csv form) like comma, semi-colon, etc you can import all the dataset by the function :

A=importdata('Path/to/file, ','); // note that here comma was the delimiter.

then matrix A is loaded to matlab workspace and you can do several interesting things with that using matlab built-in array and matrix features

no prob Markus ;)

I used this code

filename= 'size_5.txt';

delimiterIn = ' ';

headerlinesIn = 1;

A= importdata(filename, delimiterIn,'\t', headerlinesIn);

for k = [2, 4]

disp(A.colheaders{1,k})

disp(A.data(:, k))

disp(' ')

end

but it gives an error Unable to load file.

Use TEXTSCAN or FREAD for more complex formats.

I had attached my text file..

Could you please help me..

Thank you...

Yes, either you can use '\t' as tab delimiter or simply ' ' to mention space A=importdata('size_5.txt',' ');

then you can call you A as a normal matlab cell. i.e.: A(1,2) , etc

Thank you Markus and Amir. This function has worked.

But the data is imported in single column, but as my file contains 5 columns. Because i want to subtract each column with 1. As the imported data is in single array, i couldnt mention range of the column to get subtracted.

Could you guys help me for this..

Thank you..

then use readtable( function in matlab ) and specify the first line as headerline :

B=readtable('size_5.txt','HeaderLines',1,'Delimiter','\t')

in anycase check this link to understand the behaviors of the function :

Thank you so much Amir and Markus for ur kind and valuable suggestions...

Markus i used importdata function, but i change my file to .xls and it worked brilliantly.

Thank you so much....

hello

i want to import matlab file and then divide the reuter dataset into equally separated classes into positive and negtive classes  and access features. can anyone how to write code
