Vers: MathCAD Prime 7.0.0.0
See screen grab attached.
I'm not that hot on mathcad so excuse the lack of termiknowledge.
Essentially I've created a function which outputs a 'list' of values I then go on to change the input values producing new 'lists'.
I would then like to evaluate the first value of each list against the others, however, I believe the 'lists' need to be any of; an array, a vector or a matrix. Which I'm assuming they're not going by B[1]= failing to return a value.
My attempts to convert them have failed: (units are not compatible)
As you can see at the moment I've just typed out the first value of the 'list'.
Any help is appreciated.
Cheers,
J
Solved! Go to Solution.
Ok so I've found that if I define my original range as equal to a new variable it becomes a vector or array. This then means my output becomes a vector/array I can then pull values from it.
Which if you ask me is stupid all I'm doing is typing z:=x and z is now a vector/array where x wasn't.
I like your 'termiknowledge' !
But: Please attach your Prime worksheet, not just a picture.
Further: You need to understand the difference between a range and a vector.
You've created z as a range. And while the result of B(z) looks like a vector, it is not, so you cannot index it.
Success!

For some info on range <> vector see here: https://community.ptc.com/t5/Mathcad/How-to-form-a-matrix-with-variables-defined-with-range/m-p/891020#M207928
Hi Luc
As shown in my own reply all I needed to do was redefine my z range as any other variable and all was gravy.
Yep, gravy.
But bear in mind that you are now using an undocumented trick. It may become supported functionality, or become non-functional in a future version of Prime.
Success!

The (undocumented) trick to turn a range (which is kind of an implicit loop and not a set of values) into a vector is not the re-assignment to another variable but the inline evaluation immediately after the definition in the same region. If you would defined x:=0,R/10..R = then x would have been a vector right away.
The trick exists for a very long time (even back in older versions of real Mathcad) but as its undocumented its a matter to be changed without notice. So while its quite convenient, it may be a good idea not to rely on it in important worksheets which are supposed to have a long life span.
