javascript - How to call Monotonic Spline function -


let me preface with, i'm not math whiz means. interested in fitting curve monotonic spline function data.

i trying javascript version of monotonic spline function work , can't figure out how call function properly. specifically, beginning of code starts (i've never seen function named in manner before):

var cubicspline, monotoniccubicspline; monotoniccubicspline = function() {   function monotoniccubicspline(x, y) {

to me, same function defined in 2 different scopes. first doesn't take parameters , second 1 does. how around this?

i started supplying points wanted fit:

monotoniccubicspline([0,5,10,15,20,25], [0,6,2,6,7,10])

but portion of function doesn't return anything, seems if need call function same name above that. if want test out, here's jsfiddle link:

http://jsfiddle.net/sszkr/7/

any appreciated! thanks!

credit function goes to: http://blog.mackerron.com/2011/01/01/javascript-cubic-splines/

in monotoniccubicspline function declaration, can see there interpolate function added prototype , constructor function returns nothing.

so have declare new monotoniccubicspline use interpolate function.

example:

var myspline = new monotoniccubicspline([0,5,10,15,20,25], [0,6,2,6,7,10]); console.log(myspline.interpolate(3));

i'm not sure suppose interpolate function argument abscissa.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
