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)

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.
