".dat" is used as an extension by many different programs. There is no standard file format for it. You need to know the exact arrangement of data that is required by the program that will read in the data. There might already be a routine to do the saving (depending which program it is) or you might have to write one using fopen()/fwrite()/fclose() and memmapfile() might turn out to be useful.

Hi,
Thank you for your reply. Please I want to read it in C language.

fid = fopen('YourOutput.dat', 'w');
fwrite(fid, YourArray);
fclose(fid);
Note: C indexes increase fastest along the rows but MATLAB indexes increase fastest along the columns. You may wish to transpose your data as you write it.
fwrite(fid, YourArray.' );
