profreport

Generate a profile report

Syntax

profreport
profreport(basename)
profreport(stats)
profreport(basename,stats)

Description

profreport suspends the profiler, generates a profile report in HTML format using the current profiler results, and displays the report in a Web browser.

profreport(basename) suspends the profiler, generates a profile report in HTML format using the current profiler results, saves the report using the basename you supply, and displays the report in a Web browser. Because the report consists of several files, do not provide an extension for basename.

profreport(stats) suspends the profiler, generates a profile report in HTML format using the profiler results info, and displays the report in a Web browser. stats is the profiler information structure returned by stats = profile('info').

profreport(basename,stats) suspends the profiler, generates a profile report in HTML format using the profiler results stats, saves the report using the basename you supply, and displays the report in a Web browser. stats is the profiler information structure returned by stats = profile('info'). Because the report consists of several files, do not provide an extension for basename.

Examples

Run profiler and view the structure containing profile results.

1. Run the profiler for code that computes the Lotka-Volterra predator-prey population model.

profile on -detail builtin -history
[t,y] = ode23('lotka',[0 2],[20;20]);

2. View the structure containing the profile results.

stats = profile('info')

MATLAB returns

stats = 
FunctionTable: [42x1 struct]
    FunctionHistory: [2x830 double]
     ClockPrecision: 0.0100
               Name: 'MATLAB'

3. View the contents of the second element in the FunctionTable structure.

stats.FunctionTable(2)

MATLAB returns

ans = 
          FunctionName: 'horzcat'
              FileName: ''
                  Type: 'Builtin-function'
              NumCalls: 43
             TotalTime: 0
    TotalRecursiveTime: 0
              Children: [0x1 struct]
               Parents: [2x1 struct]
         ExecutedLines: [0x3 double]

4. Display the profile report from the structure.

profreport(stats)

MATLAB displays the profile report in a Web browser.
