I'm getting following error: Array indices must be positive integers or logical values.

Hi, when I test following code whit some easy nubers I get the error: Array indices must be positive integers or logical values. (in the line I(0) = b - a) I already tried clearing the workspace but the same error keeps popping up. What else could be the problem?

function  [H] = ComputeWeights(a,b,x)

n = length(x)-1;
I = ones(n+1);
I(0) = b - a;
I(1) = 0;

for i = 2:n+1
    I(i) = ((b-a)*((-1)^i + 1))/(2*(1-i^2));
end

for i = 0:n+1
    x(i) = ((2/(b-a))*(x-a))-1;
end

T = zeros(n+1,n+1);
for i = 0:n+1
    for k = 0:n+1
        T(i,k) = cos(k*acos(x(i)));
    end
end

H = linsolve(T,transpose(I));
end

Indexing in MATLAB starts with 1, not with 0.
