I am struggeling with importing data from a .txt file in my script, and i believe it is due to a '$' in my first coloumn. I have tried using csvread, textscan and importdata. The only thing i got to work was importdata, but it ignores the delimiters.
This is the command i use: "test = importdata(fullpathname,',')"
It gives me a 1291x1 array, which should have been a 1291x10.
I have attached the file im trying to import. Anyone got an idea how to import the data in different coloumns?
Thanks!

Have you tried the readtable() command yet? http://www.mathworks.com/help/matlab/ref/readtable.html
It works very well with delimited files. It also allows you to specify an optional 'Format' if it doesn't work correctly out of the box.

I got a little problem with the format. I am trying to get the numbers from my data alone, but when i use "T = readtable(fullpathname,'Delimiter',',','ReadVariableNames',false,'Format','%n%n%n%n%n%n%n%n%n%n')" i get the following message: "Error using readtable (line 135) Unable to read the entire file. You may need to specify a different format string, delimiter, or number of header lines.
Caused by: Reading failed at line 1. A field on that line may have contained the wrong type of value."
If i leave out Format there is no problem, but as soon as i insert Format it goes wrong. Any idea what is wrong?

For the format string, try something like:
'$%n%n%n%n%n%n%n%n%n%n#'
And since all of your numbers look like integers, maybe consider replace the "%n" which signifies a double precision float with %u for unsigned integer or %d for signed integer.
