Need help solving a pde with finite elements in matlab
 
<p>I have an initial value problem u''''=f </p>

<p>with u(0)=u'(0)=u(1)=u'(1)=0</p>

<p>It comes then by multiplying with test function v and integrating to following formulation:</p>

<p>integral( 0 to 1) u''v'' dx= integral (o to 1) fv </p>

<p>So the basis function are polynomials of degree 3
And those polynomials can be solved exact with the simpson rule.</p>

<p>So I want to write some code to get the stiffness matrix for this..</p>

<p>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.</p>

<p>looking forward for any help!</p>
