Is it possible to extract features from program dependency graph ?

Hi,

I am a bignner in matlab. I have to extract features/metrics from program dependency graphs generated by using a tool. These program dependency graphs are generated from c code. I would like to know, is it possible or is any way to extract features/metrics from these program dependency graphs by using MATLAB.

Features like

number of Assign- ments that come after Declarations,

number of Declarations coming after Control (e.g. i < count, for, while, if, switch etc.),

numbers of times nested iterations occur,

numbers of times nested selections occur

If is it possible then please guid me!

It is probably possible. How easy it is would depend on the format of the files being analyzed.
