I took a look at the numerical methods book, but it seems oriented to actually evaluating an infinite series up to a certain accuracy. With formal power series all we want are the coefficients. For example, consider the series
S = 1 + x + x^2 + x^3 + ... The coefficients are an infinite list [1, 1, ...]. What I need is a class for S that would allow me to perform operations such as addition, multiplication, etc. Thus I would like to able to do S * S and get the infinite list of the coefficients [1, 2, 3, 4, ...] and view say the first 10 or perhaps the nth coefficient. Your LazyList looks promising. To create the series this seems like it would work. s := LazyList wholes collect: [ :n | 1 ] But defining the operations is the difficult part. I would like to look at your package, but I need some help. How can I download your package from smalltalk hub so that I can examine it, play with it, but eventually easily remove it if I want. As you can tell, I have just started learning Pharo. -- View this message in context: http://forum.world.st/Is-lazy-evaluation-of-infinite-series-possible-tp4897956p4898028.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
