Array indices must be positive integers or logical values.

Why do i have this problem? Array indices must be positive integers or logical values.

Here is my code.

Thanks!

H(0) does not exist in MATLAB. Array indices start with 1.

And if inv(K-W^2*M) is a matrix, you cannot save it in a scalar H(W). You will have to use a cell array:

H{W} = inv(K-W^2*M)

Try

for W = 0 : 500
    H{W + 1} = inv(K-W^2*M);
end
