Matlab測量時間的方法

發表 由 Admin 于 周四 6月 17, 2010 5:43 pm

help cputime
CPUTIME CPU time in seconds.
CPUTIME returns the CPU time in seconds that has been used
by the MATLAB process since MATLAB started.

For example:

t=cputime; your_operation; cputime-t

returns the cpu time used to run your_operation.

The return value may overflow the internal representation
and wrap around.



help tic
TIC Start a stopwatch timer.
TIC and TOC functions work together to measure elapsed time.
TIC saves the current time that TOC uses later to measure
the elapsed time. The sequence of commands:

TIC
operations
TOC

measures the amount of time MATLAB takes to complete the one
or more operations specifed here by "operations" and displays
the time in seconds.
