bending moment and shear force diagrams in matlab

Hi, all. I have a to do a project which is to make matlab plot bending moment and shear force diagrams for the most generel case.But I dont know where to start. I have extremely thick matlab books but I cant find it within them.Can smb advise me some sources about this situation?

Well, look in your mechanics of materials text for sample of the graph form you're after and then think of how to implement that in Matlab. There isn't, as far as I know, a specific function prepackaged altho if it's allowed by your homework ground rules, you could check the File Exchange for a submission--might have been something done there. Or, I suppose one of the mechanically-oriented toolboxen might have some specialty graphs; those I "know nuthink'" about...

help graph2d  % get you started on the various types of plots in Matlab

Big Hint:

do stairs % may be of interest particularly for the shear force diagram

Hi, There is an example of beams in matlab. Can somebody articulate it. What is setbeam(EI, L, BC_Spec) I know it is an array but I do not know it is physical meaning. what is Load_Spec = [0 0.5 1.2]; and here beamf(Load_Spec) is assigned to y but what is plotbeam(y)
