Summary: "Let $f$ be an arithmetical function. The matrix
$[f(i,j)]_{n\times n}$ given by the value of $f$ in greatest
common divisor of $(i,j),\ f((i,j))$ as its $i,j$ entry is called the
greatest common divisor (GCD) matrix. We consider the generalization of
this matrix where the elements are in the form $f(i,(i,j))$.''
