doubt w/ code question

Hey guys,

I need to use matlab code related with the monte carlo method applied to human tissues (MCML*).

I found this code http://www.mathworks.com/matlabcentral/fileexchange/13471-monte-carlo-simulation-for-photon-migration-inside-biological-tissue-version-1-3

i am completely new in matlab and i do not understand how to use it. For many days, i have been studying it. for now i know that:

-i should start by running the file test_MC.m

-theoretically, with monte carlo method I get to calculate: fluence**, reflectance, transmission

-for what i understand this code gives results related with reflectance and transmission. But i need the fluence. Does anyone understand how can i get it?

Even if not, can anyone point out some key ideas about the code, so that i can study it more and try to find something?

Thank you so much for any information at all. it would be a lot! thank you!

*Monte Carlo Modeling of Light transport in multi-layered tissues.

**theoretically: units are Joules or watts

As mentioned in the comments on the FEX web page referenced in your question, it is not a well documented submission (and even an obscure DLL). You might want to contact the author if you need more information.

In the mean time, I guess that it wouldn't hurt learning MATLAB basics, and how to produce distributions relevant to your input parameters. Once you master this, it is not very complicated to implement a Monte Carlo simulation by yourself (even without using specialized toolboxes). The wisdom behind these "cheap advices" lies in the fact that authors are not always very responsive, especially when they submit black boxes, and you may not receive any feedback. And even if the person answers and provides some information, not really knowing how it was built won't help you a lot in the sense that it doesn't look like a well peer reviewed and maintained/supported tool that you can rely on for doing research.

If your Mathworks account is associated with your MATLAB license, you should have access to

http://www.mathworks.com/help/pdf_doc/allpdf.html

which contains MATLAB+toolboxes documentation. For learning the basics and more, I recommend MATLAB Prime, Mathematics, Programming Fundamentals, and Data Analysis in the MATLAB section. Once you know the basics (I'd say after the Primer), lookup the documentation of functions RAND, and LOGNRND for example, by typing

 doc rand

and

 doc lognrnd

in the command window.
