Hello
I am using dlmread to input data from .txt file. Actually file was having some character headers and texts. But as we cant use dlmread for file having texts in it. I deleted all the text in the file. So now there is only numerical data, 5rows and 12 coulumns. I want element which is at point 1st row and 10 th column. So the command I used is
a= dlmread('file name', '', [0 9 0 9])
But I am getting error as mismatch in file format and string.
What might be the reason?? Please reply soon. Urgent help required.

Please post part of the content of your file, also with headers if you like and format it with the {} code button: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup#answer_18099

Ok. I got the mistake..
Can any one tell me which function I can use to remove all the hyphens in my .txt file.
The column of hyphens in my file is causing error in dlmread.

Is the hyphen used as the delimiter? If yes, use a=dlmread('filename,'-',[0 9 0 9]);

No hyphen is not delimiter. comma(,) is delimiter.
in my dat I am having column of hyphens(its automatically generated data so whenever there no data element available it generates hyphen)

a=magic(12);
b=a(1,10)
dlmwrite('test.txt',a);
r=dlmread('test.txt',',',[0 9 0 9])
