problem using textscan: doesnt actually scan anything.

hi. I am trying to write a program that reads stuff from a text file. as a simple example, i created a .txt file by the name "niv" that has a row:

1 2 3 4

and want to read it into an array. i tried this:

fopen('C:\Users\Lab\Desktop\niv.txt')
num=textscan('niv.txt','%d')

but afterwards, num is empty.... please help !

thanks .

Hi,

try

fid = fopen('C:\Users\Lab\Desktop\niv.txt')
num=textscan(fid,'%d')
fclose(fid)

Be aware that "num" is a cell array afterwards ...

You are providing a string 'niv.txt' as the first argument to textscan(). When you provide a string there instead of a file identifier number, it is the content of the string that is scanned rather than the content of the file.
