Matlab Wall Clock Time

A simulation stops when it meets any of the criteria specified by stoptime maximumnumberoflogs or maximumwallclock however if you specify the outputtimes property of the solveroptions property of the configset object then.
Matlab wall clock time. However if i measured it using a stopwatch i got 27 sec as the time. Knowing the execution time of your matlab. T cputime returns the total cpu time used by matlab since it was started. The returned cpu time is expressed in seconds.
I tried to measure the time taken by a program to execute in matlab by using the tic and toc function. Example c tf clock returns a second output argument that is 1 true if the current date and time occur during daylight saving time dst in your system s time zone and 0 false otherwise. To measure the cpu time used to run your code place two calls to cputime before and after the code and then calculate the difference between the returned values. Use the wall clock time directly from the processor.
The documentation for the matlab function clock describes exactly what the elements of that vector represent. Total elapsed wall clock time. This option is the most computationally expensive measurement and has the most impact on. The documentation page to which you linked is for the simulink source block not the function in matlab.
I am trying to simulate a model using the simulink desktop real time in external mode and as mentioned in the title i have an s function block. This property sets the maximum elapsed wall clock time seconds criteria to stop a simulation. Useful clock resolution is around 10ms on windows machines and better in linux or macos. This number can overflow the internal representation and wrap around.
Each call to cputime returns the total cpu time used by matlab up to the point when the function is called. The clock function calculates the current date and time from the system time. The mex files that are used by the s function block are created using c source. To measure the cpu time used to run your code place two calls to cputime before and after the code and then calculate the difference between the returned values.
Maximumwallclock is a property of a configset object. Each call to cputime returns the total cpu time used by matlab up to the point when the function is called. Sometimes your power savings settings or use of multiple processors influence this measurement timer real use system time reported by the operating system. The returned cpu time is expressed in seconds.
I got 0 7283 as a value. Cputime returns the total cpu time in seconds used by your matlab application from the time it was started.
