I have an initial value problem u''''=f
with u(0)=u'(0)=u(1)=u'(1)=0
It comes then by multiplying with test function v and integrating to following formulation:
integral( 0 to 1) u''v'' dx= integral (o to 1) fv
So the basis function are polynomials of degree 3 And those polynomials can be solved exact with the simpson rule.
So I want to write some code to get the stiffness matrix for this..
I find it very hard to start with ..I don't have much experience in Matlab and would kindly ask you to help getting me started.
looking forward for any help!
