This value must be a scalar error

[BillDumke]

I need to have a function that works with a vector that could be any length. How do I get rid of the range variable requirement? See attached Mathcad 11 doc.

Like the attached?

I have used the pre-defined vec function in the collapsed area.

Mike

[BillDumke]

I see the vec() function in the utiltities list, but I don't see where you used it.

[MikeArmstrong]

I used it to define I.

Mike

[BillDumke]

I see that. But nothing else works on the sheet after that. Get "Illegal Function Value" error for Vf(I).

[MikeArmstrong]

Sorry Bill,

I didn't even look down the page after the vectors. I am mad busy sorry.

See attached.

I see the Vf program, but the numbers are to the 22nd power and 0 does not exist for I < 0. I can wait till tomorrow if it will help you. Thanks for the effort.

Are your number correct in the first worksheet you posted?

Mike

[BillDumke]

Yes, it plotted correctly as well using range variables.

[BillDumke]

I think the problem is the program does niot replace the complex numbers below zero with zeros.

Try the attached Bill.

Works Great! Thank you very much for taking the time.
