Solving large system of linear equations

6 views (last 30 days)
How to solve a large system of linear equations in MATLAB? In particular I have 31 equations and 31 unknowns and I can write these equations recursively. Say I have equations of the type c(n-1)-c(n)+c(n+1)= 0, n varying from 2 to 32 where I know the values of c(2) and c(32).

That is the case but I need to calculate c(0) and c(32) as well, but because of MATLAB indexing, it means I need to calculate c(1) and c(33) with c(2) and c(32) being known.

c(1,1)=5; c(n,1)=10; %Example data
T=toeplitz([-1,zeros(1,n-3)], [-1,1,-1, zeros(1,n-3)]);
c = 32×1
5 -10 -5 5 10 5 -5 -10 -5 5
