Converting range variable into a vector, ultimately to find root

Hi All,

Is there an easier way to convert a range variable into a vector? That is, suppose we have a list of data (perhaps huge) in a single table over a range. Infact, this range variable is the output of a part of programming in mathcad. How to convert this in to a vector? Once I can convert this into a vector, then I can easily locate roots using curve "fitting".

If you have a range variable, say i:=0:10, you can create the vector x with values 0 to 10 simply by x[i:=i (where the '[' symbol provides a subscript in Mathcad - it's a pity the text formatting in these posts doesn't allow subscripts given the frequency with which they're used in Mathcad).

Alan,

Just one of many problems with the website. It surely isn't hard to implement subscript/superscript formatting options.

I've managed to work out. I don't know what was the error though. Writing f subscript i and equating it to f(i). Then computing f gives me the vectorised form, so simple. It didn't use to give me before, however.
