triangular mesh code for finite difference element method

Write a code that generates automatically a structured nite element mesh with 2N^2 triangles.

The code should generate two arrays triangle, nodes.

. nodes(k,1) is the x coordinate of the node number k.

. nodes(k,2) is the y coordinate of the node number k.

. nodes(k,3) is equal to -1 if the node is constrained (i.e. on the boundary of the domain) and +1 if

the node is a free node (i.e. interior to the domain).

. triangle(k,i) is the global number of the local node number i of element k, for i = 1; 2; 3. The local

numbering is done counterclockwise, starting with the node at the square angle of the triangle.

Test the code for N = 2 and N = 4: give the entries of the arrays described above and plot the grids.

Please reply as soon as possible. The deadline is 2-3 days from today.

Thanks.
