MATLAB Programming Fundamentals - MathWorks

The Profile Summary report presents this information.

Column Description

Function

Name

List of all the functions called by the profiled code. Initially the functions

appear in order of time they took to process.

Calls Number of times the profiled code called the function.

Total Time Total time spent in a function, including all accessed child functions, in

seconds. The time for a function includes time spent in child functions.

The Profiler itself takes some time, which is included in the results. The

total time can be zero for files whose run time is inconsequential.

Self Time Total time in seconds spent in a function, excluding time spent in any

child functions. Self time also includes some overhead resulting from the

process of profiling.

Total Time

Plot

Graphic display showing self time compared to total time.

In the summary report, you can:

• Print the report, by clicking the print button.


• Get more detailed information about a particular function by clicking its name in the
  Function Name column. For more information, see “Profile Detail Report” on page
  28-9.


• Sort by a given column by clicking the name of the column. For example, click the
  Function Name link to sort the functions alphabetically. Initially the results appear in
  order by Total Time.

Profile Detail Report

The Profile Detail report shows profiling results for a function that MATLAB called while
profiling.
