GCN algorithim에 대해서 정리해서 설명하면 다음과 같이 설명되어질 수
The 1-dimensional mass transport equation is expressed as follow :
In GCN, we used time weighting factor to generalize the discretization
method for the time domain. So, forward, backward, and central finite
difference analogue is defined by the following value of time weighting
The analogue of GCN becomes as follows :
Let's define the following coefficient to consist the Tridiagonal Banded Matrix.
Use the Thomas Algorithm to solve the above system of
After the assembling the above analogue for the whole nodes, the
left hand side matrix becomes Tridiagonal Banded Matrix. In which,
components of each equation are expressed by the following
