Hi I am very new to MathCad and have hit a brick wall with changing a range variable to a vector. I'm currently using Prime 6.0 in trial form.

 

my understanding is you define a range then define your vector based on that range e.g

N:20

i:1..N

a[i:i 

 

I start the range with 1 but I always get the 0 index appear in my vector. Am I doing something wrong here?

It works OK if i input the vector myself

So I'm pretty sure its the range to vector technique I'm using causing me issues.Apologies if this is super easy I just cant see it right now.

 

Thanks for your help in advance.

 

Any help would be appreciated.

Mathcad assumes an origin of 0 by default.   At the top of your worksheet enter ORIGIN:=1 if you want the index to start at 1.  (Note use all upper case for the word ORIGIN).
