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.

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])
