You need to be basing your factor on the Ab matrix rather than the A matrix; your (3,2), (2,3), (1,3) and (1,2) values are going to change as time goes on. It looks like you started to fix this issue during your forward elimination, since you included the Ab properly in that factor calculation. As a side note, you may wish to normalize at ...

WebThe forward difference is to estimate the slope of the function at xj using the line that connects (xj, f(xj)) and (xj + 1, f(xj + 1)): f ′ (xj) = f(xj + 1) − f(xj) xj + 1 − xj The backward difference is to estimate the slope of the function at xj using the line that connects (xj − 1, f(xj − 1)) and (xj, f(xj)): http://matlabmarina.com/pdf/matlab%20marina%20differentiation%20primer.pdf
