Question

Mathcad prime2.0 limitation here...on maximum number of row index

Please see my attached prime 2.0 file. I wrote a modified program in mathcad prime2.0 based on Harvey Hensley stoich_mod mathcad 15 file.

It turns out I have to break my program in two part or mathcad prime2.0 would not do it. It says row index out of range if I put all the operation in 1 program. Then it turns out it is ok if I separate it into 2 peices.....how strange...anyone know what is going on here?

I literally just break my program into two half without doing additional work...why is prime2.0 so strange...Or is it just the problem of my program..

HI Henry,

I'm not sure why this works in one case and not in another , but part of the problem appears to be that you are taking a column vector from your complete array and then indexing the rows in it using the number of columns to do so.

Obviously , once you exceed the number of rows , prime should stop & report an error.

In the case of the whole program , I think that is what happens.

However I would also expect that the same thing should happen even if you split the program!

A careful inspection of the program will be necessary to ensure that you are getting predictable answers4

I found the problem.

all I have to do is use a line

v3<---v3

before the second half of my program

and it solve everything!
