Quick question; Proper way to define multiple vector values

[dsochor]

What is the error with the syntax in the attached program? I am attempting to define multiple values of a vector depending on the previously assigned variables. I am expecting the vector to have two rows but only one results.

Post your sheet. From the picture it's difficult to see what is an index and what is a literal.

Although the above is in Mathcad 15, the same applies to Prime.

Found the culprit. The function delivers the last statement as result.

Add a last statement that returns the desired result,

such as:

Note that Mathcad usually starts vectors and matrices at index 0

Another quick question (want to avoid creating another topic). Why does Mathcad not see NaN results? In the attached jpeg, c_ac is NaN but the if statement won't recognize it.

I guess it's one of those.....Prime things. This is what Mathcad say about it:

Success!

Must be your older version of Mathcad.  Here's Mathcad 15:

You have to use the IsNaN function:

Perfect, thank you!
