You can read that file using textscan. Read about it.

Thanks but sorry, textscan couldnot read it.
Can you show how textscan is able to read this data?

Okay,
Matlab cannot read .nas files, so one needs rename the .nas files to .txt (or similarly suitable extensions), and then read the .txt files using textscan
See below for an example
filename=('pwd')
FID=fopen(filename);
datacell = textscan(FID, '%f%f%f%f', 'HeaderLines', 53, 'CollectOutput', 1); %%%removing the first 53 lines that are headers
data=cell2mat(datacell)
fclose(FID);

no, when you fopen you can give any file name. fopen does not use the file name to identify the type of the file in any way.
