Dear Community
I need help on how to convert data that are coming from a function "150" point into a vector of one column, My target is that after I finish the function I need to process this data by comparing them to a constant and divide these data based on the comparison
My work is as following
1) I have a range called z, this range is then used in a function
2) this function e(z) outputs are a range based on z
3) I then need to compare all the values that are in the range of the fn e(z) to a constant c
4) for the values that are less than c; I need to report them as is
5) for all the values that are greater than c I need to report them as c+1
6) then I want to combine all the values again in the order starting from values less than c to values greater than c
Please guide
Thanks
Unfortunately, I'm without Mathcad at the moment, so will have to describe the process.
It's usually better to work with vectors than range variables for this kind of poblem or write a program, primarily because indexing with non-integer variables isn't possible directly and it requires a bit more work to set things up (nothing too difficult, just annoying).
So I'll give a vector procedure. First, define your range variable z
z :=x0,x0+step .. x1
Now you need to convert your range z to a vector. There are several ways to do this, but I find this the simplest (vec is so iseful that I define it in my Normal template).
Have a look at the above thread and copy the function vec into yor worksheet.
Then convert z to a vector
z := vec(z)
Aply e to z
v:=e(z). -- select the whole of the expression e(z) and apply the vectorize operator to it; this ensures that you apply e to each element of v rather than applying it to the vector.
Vector v contains your results.
Next, make use of Mathcad's Boolean operators and type
c := whatever value you want ...
v := v + (v>c).
Again, select the whole of the right hand side of the definition and apply the vectorize operator to it. Mathcad returns 1 if a Boolean is true and 0 if it's false. So this expression will add 1 to every value greater than c.
The next thing is to sort the data. As all values > c are greater than those that aren't 
, all we need do is write
v := sort(v)

Like this?
Needless to say, E contains more that 16 values, 150 to be exact. But the last values are (too) close to zero:
Depending on your range, you may be able to directly use the above.
Attach your worksheet if you need further help.
Success!
