Hi,  
When I run getsecstick I get a value of 1e-9. This suggests to me that the   
getsecs clock is accurate to 1 nanosecond. But when I run getsecs, I get   
values out to 4 decimal places, suggesting that the clock is accurate to 100   
microseconds. What is the correct resolution of the clock? Is there any way to   
see the getsecs results out to 9 decimal places? thanks,

if you want MATLAB to print a number to more than four places, use a   
formatted print command, e.g.  
  
fprintf('%.9f s\n',getsecs);
