Accepted Answer

If it is not on MATLAB path, you can still read it by specifying the correct Absolute or relative paths. For example, the following uses an absolute path

dlmread('C:\{path_to_folder}\ann.txt')

Where 'C:' is the drive in which folder is located. Similarly, on Mac or Linux, you will need respective absolute paths.

an.txt

In this attachment first row contains the characters then how can i specify them in syntax "dlmread(filename, delimiters, r1 c1)" to read all data?

dlmread() can't read non-numeric data. In your file, the first column contains dates. For you case, more appropriate is

data = readtable('an.txt')
