Last homework for the class. Just have a test left. :D
PartDiffEq.c - Example from book
PartDiffEq_HW1.c - Problem 1 from handout.
|Really bad picture, until I scan in the page, problem 1 layout and actual results|
Obligatory use of my matrix library:
gcc matrix.c PartDiffEq_HW1.c -lmSave the results to a text file:
./a.out > PartDiffEq.results.txtNot sure I have this down pat yet. When the equation is not equal to 0, I am not sure what to do, the HW1 I had a formula to get the exact answer, and I calculated back to figure out what to subtract from the output vector to compensate for that.
What we used the formula for was to find the temperature of an insulated thin rectangular plate that had reached a stable temperature. You have to figure out the formula for the temperature of the edges, make a grid of points inside and create a matrix for the points, then create a vector of the outputs, find the inverse of the matrix and then calculate the solution vector.
