what the role of I in this code ?
can you explain this line in detail
fixedDof=find(xx==min(nodeCoordinates(:)) ...
| xx==max(nodeCoordinates(:)))’;
L=90;
numberElements=3;
nodeCoordinates=linspace(0,L,numberElements+1);
xx=nodeCoordinates;
% boundary conditions and solution
% prescribed dofs
fixedDof=find(xx==min(nodeCoordinates(:)) ...
| xx==max(nodeCoordinates(:)))’;
prescribedDof=[fixedDof]
% free Dof : activeDof
activeDof=setdiff([1:numberNodes]’,[prescribedDof]);

The function names seem to be pretty clear on what they are doing, but if you have any doubts, look up the functions in the documentation to see what they do..
