Answer 1

[Sean de Wolski]

as long as

class(your_result)

is 'double' it is long.

please clarify....

[Sean de Wolski]

MATLAB uses long (ieee 754 double precision floating point (64 bits)) to begin with. Unless your data is something else, IT IS LONG. It may not be displaying all of the digits, but they're there.

To visualize:

format long

disp(your_result)

And use class() as above to verify

[Matt Tearle]

or use something like fprintf('%16.13f',x) to see the result to whatever precision you want.
