In dealing with continued fractions in LaTeX, I've become less and less enamored of the
\cfrac construct. Especially in my case where I deal with complicated numerators and denominators, listing a few terms can get unwieldy.
I encountered a nice notation for CFs in Lorentzen and Waadeland's "Continued Fractions with Applications" that seemed to be adaptable to my needs. I have no digital copy of the book, so I offer Wolfram's approximation on how this operator is rendered:
(the only difference is that the b terms come before the a terms, and they are separated by a backslash (this is why I asked this question, so I now know how to render the operands and the delimiters properly))
My question now, then, is how can I construct a "continued fraction operator" that acts like
\product? Somehow, trying to use a large letter K and then putting the limits as over- and underscripts has been a bit of a mixed bag (and of course, if the operands themselves are fractions, I have to manually tweak the size of the "K" again!). Might there be a more elegant approach to this?
