Solving large system of linear equations

4 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).

Are you sure you don't mean, you know the first and the last point, c(1) and c(32)? You're trying to solve for c(2)..c(31) correct?

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
