Looks OK to me. All * are there and since eta[m] is a Mathematica
function call format, a translation as eta(m) in C is OK as well, as
this is the way functions are called in C. Perhaps you meant to index
an array? In that case you should double brackets ==> eta[[m]], which
would become eta[m] in C.
