Hello,
Is there an interpolation function that can accept a 2-dimensional array of data (in my case, it will be comprised of a series of dates and corresponding dollar values) and return the interpolated values in between, along with a graphical rendering of the output? For example:
Input:
(1/1/14, $2.50),(1/5/14, $2.53),(3/7/14, $3.75),etc…
Output:
1/1/14, $2.50
1/2/14, $2.51
1/3/14, $2.52
1/4/14, $2.52
1/5/14, $2.53
1/6/14, $2.55
…
3/6/14, $3.73
3/7/14, $3.75
etc…
Thank You,
Jesse
First, the data would have to be in Mathematica’s syntax:
my data = { {{2014,1,1}, 2.50}, {{2014,1,2}, 2.51}… etc }
This can be plotted with DateListPlot, but …
the function Interpolation won’t take that date specification however, so we have to convert it to a simple number. There’s a number of ways to do this.
One way is to apply AbsoluteTime to the list which represents the date.
If you’re new to programming with Mathematica, take a look at the Virtual Book for an introduction: http://reference.wolfram.com/mathematica/howto/UseTheVirtualBook.html
