You can use Matlab’s profile function to get some useful information about your scripts.
For example, running the profiler around CellOrganizer’s demo2D00
>> profile on; >> demo2D00(); >> profile off; >> profview
will produce a report similar to this one
Report from running a profile on demo2D00.
But sometimes you want something visual. And…. here comes GraphViz-like tools for MATLAB to the rescue!
GraphViz-like tools for Matlab “[…] creates a GraphViz dot language representation of the dependencies of a function.”
Before we start you need
I tested the toolkit in Matlab 2014b for Mac. This shell script will download the toolkit and its two dependencies. Assuming you are using HomeBrew, it is will also install GraphViz
wget -nc http://www.mathworks.com/matlabcentral/mlc-downloads/downloads/submissions/27608/versions/2/download/zip/docsgen_dot_tools.zip unzip -o docsgen_dot_tools.zip rm -f docsgen_dot_tools.zip wget -nc http://www.mathworks.com/matlabcentral/mlc-downloads/downloads/submissions/24652/versions/4/download/zip/drawDot.zip unzip -o drawDot.zip rm -f drawDot.zip wget -nc http://www.mathworks.com/matlabcentral/mlc-downloads/downloads/submissions/17291/versions/8/download/zip/fdep_21jun2010.zip unzip -o fdep_21jun2010.zip rm -f fdep_21jun2010.zip brew install graphviz
If the above commands were successful, then you should see the following files as well as the dot binary.
$ ls drawDot.m hfdep mGraphViz.m script.sh tfdep2.m tfdep4.m fdep.m license.txt mkdotfile.m tfdep1.m tfdep3.m $ which dot /usr/local/bin/dot
This example makes the graph from a file in my desktop. Make sure the file save in the variable ifile exists before running.
echo " ifile = '~/Desktop/script.m'; if exist( ifile ) ofile = 'graph.dot'; txt = mkdotfile( ifile, ofile ); system( [dot -Tjpg graph.dot -o graph.jpg] ); exit;" > make_graph.m end matlab -nodesktop -nosplash -r "make_dot_graph;"
The result from running the script above is the graph below
