Is this one row out of many?

No.. These are many rows. Actually its an array in mupad which i had wrote in a text file. Now i want to read it from matlab and want to extract each number seperated by comma...

Why not just

 str=fileread('test.txt');        %read file
 str=regexprep(str,'[^0-9 ]',''); %remove everything but digits and spaces
 data=str2num(str);               %convert to numbers

Only when things like exponential notation come into play, this will be more tricky. But to this stage, that's the easiest way I think.

Thank you sir... It hepls me a lot... But it gives me the array in the form 477181869995.000 . To overcome it i used db = cast(data,'uint64'). And now i got the array as desired.
