I came across a strange effect while reading in some data from an Excel sheet and changing some elements which where formatted as text in Mathcad back to be numbers. Mathcad woul not recognize the resulting matrix/vector to be a matrix of scalars (while it is, or at least should be).
See below and attached a simplified example. Can anybody explain that strange effects?
BTW, the same sheet converted works fine in Prime2.
Addendum: If you make the second assignment work as described by pressing F9 and you move arround the first V^2 assignment, it works, too!!????
The German error message is something like: "The object reference is not set to an instance of an object". Obviously users are not expected to ever see this message.
(Remark: The absolute value has to be set from Determinant to absolute value)
