How do I create a function that solves systems of linear equations of N size?

function [findV] = size(N)
A=2*diag(ones(N,1))-diag(ones(N-1,1),1)-diag(ones(N-1,1),-1);
F=[1:N]';
findV =A\F;
end

Is it possible to make a function like this? That takes in a variable N and calculates V from A and F.

"Is it possible to make a function like this?"

Yes. Just name it something else, since size() is a built-in function.

x = mySize(10)
function [findV] = mySize(N)
A=2*diag(ones(N,1))-diag(ones(N-1,1),1)-diag(ones(N-1,1),-1);
F=[1:N]';
findV =A\F;
end

Result
