Hello Andy,

Well it sure looks like a bug. Here's a clue: I got function 1 to behave
normally by simply replacing the internal variable phi (f CTRL-G) by a
non-Greek variable name. What does that say?

I hope this helps,
Bill

[mathcad] Mathcad bug or programming error?

Hi folks,

The attached v11 worksheet contains two versions of a program, that I
believe to be trivially different. The output from the two versions is
utterly different. I spent altogether too long trying to find the error of
my ways in one version, before scraping the barrel of reformulation and
finding it not to be empty after all.

I seek opinions on whether the difference in output is due to Mathcad bug
or programming error. If the former is the case, it is a pretty toxic bug
(which may of course have long since been squashed). Can anyone please
either point out my error, or test these programs in the current version
of Mathcad?

Andy

Product Reviews

"Our work ranges from complex medical imaging research to large-scale mapping and diagrams and we need a tool that is able to handle anything we investigate. With Mathcad, we are able to manipulate and analyse our data quickly while at the same time documenting our work, for sharing and publication. We also use it for pilot studies conducted in support of research grant applications. It is an end-to-end tool for research and development."
Dr. Kenneth Castleman, President of Advanced Digital Imaging Research (ADIR), Houston, Texas

"Mathcad is an integral product for my work... With Mathcad, itís easy to disseminate design calculations because the documents look like real math. Thereís very little I canít do in Mathcad. The main benefits come from the format, which resemble a typed set of calculations. These programs are easier to develop by engineers and easier for others to follow and review since the logic is expressed in a familiar manner. The format is what places Mathcad head and shoulders above other programs of a similar function."
