eval(['30',ps])%30 picoseconds

ans =

Actually if i write your method or directly write 1e-12 then in long format it matlab give 9.9999999999999999999e-11 instead of 1e-12

MATLAB does not have any default time unit. Individual routines have time units. Routines that deal with dates use number of days and fraction of days; routines that deal with pausing or waiting use seconds (and those routines are not able to get picosecond resolution.)

If you were to give more context, we might be able to make a suggestion.
