MATLAB: How can I measure the real time taken by a simulation in case i use a simulink model

simulationsimulinktime

how can I measure the time taken by a simulation in case i use a simulink model? (as using tic,toc in .m files )

any comments/answers in this regard is greatly appreciated

You still use tic-toc and run the simulation from MATLAB:

   >> tic; sim(bdroot); toc

Or, use the Simulink Profiler. Turn it on by selecting Tools>Profile in your model. The next time you run your model, and HTML report is automatically generated and opened at the end of simulation. The "Total recorded time" (or the row corresponding to "sim") is the total time taken for simulation.

Hi Martin,

no, tic/toc has no influence on performance.

MATLAB: Can Accelerator work on model with algebraic loop

Starting in R2011b, Accelerator Mode Now Supports Algebraic Loops.

This is strange - if you are not making any changes to your model between runs, then the Accelerator target should not rebuild. Perhaps you should report this as a bug to MathWorks Tech Support.

Regarding your question about whether you might be better off with Normal Mode simulation - it depends. Yes, there is an initial overhead for generating and building code in Accelerator mode, but if your simulation is very long and expensive, then that initial overhead may be relatively cheap. The best way to figure out is to time your simulation. Using the tic-toc commands:

   >> tic; sim(bdroot); toc

in both simulation modes and see which works out faster.
