HI.. I'm beginner on Matlab and i'm wanted to convert my data containing 10,000 values in a single row in text file. I have load that file in matlab now I want to convert that file to array of type double. I have applied the following command for that purpose
new data= double('file name')
It has convert the data to type double but reduce it to only 8 values. I can't understand why it convert the 10,000 values only to 8.

Because you just converted a character string, 'file name', to a double of the ASCII values of 'f', 'i', 'l', 'e', and so on. You did nothing whatsoever to read in the contents of the file. Try dlmread().
