How can I do this in Mathematica:

r=Range[0,20,0.13]; fr = HeavisideTheta[r]; data = somecoolfunctionsinmathematica[r,fr] 

So that data now is in the form useful to Fit: {{r_1,fr_1},{r_2,fr_2},...}

Thanks!

This is the correct way to use Table if you prefer it to Map:

Table[{i, HeavisideTheta[10 - i]}, {i, 0, 20, 0.013}] 
0

I've found it, albeit syntactically a bit... involved (but I've seen a lot worse):

data = Table[{r[i], HeavisideTheta[10-r[i]]}, {r[i], Range[0, 20, 0.013]}]

    That's alright. IMHO taking a procedural approach when functional methods are available is a bit of a step backwards, but whatever, right?2011-11-11
