Homework Help: Structural Matrix Analysis

Hi,
My question isn't about a specific problem in general so I apologies if I have Posted in the wrong section. Basically I have just started a course on Structural analysis, and we have been using the flexibility method to solve all of out problems in matrix forms.
All of the problems we have had a look at have been plane Trusses, Beams, Frames (most have been Statically determinate, just started SID's tho).

I was hoping somebody here might have material/link to some good examples of such problems being solved with the matrix approach. The text book I have lists a few examples but since we haven't been given many in class to begin with, I need to find some more simple applications of the process in order to understand it more as I feel the course I am enrolled in isn't providing enough material on the topic .

I have an assignment due in about 10 days which I would like to post up on here once I have a decent attempt at it.

Once again sorry for not posting a more specific problem, but this method of analysis has me quite confused at the moment. Any help would be greatly appreciated,

Thank You
Regards Elbarto
