[mathcad] Re: Range Variable Problem
Author: Bill Dumke    Posted: Tue, 21 Mar 2006 20:51:18 -0600
The idea here was to find the magnitude and argument and then apply a
polynomial regression to each seperately. (Trying to use a regression
rather than a filter to get away from the time delay problem in a filter
messing up the accuracy of the argument.) The example I showed you was
an oversimplification. I am sorry it got hung up on a non-problem.
(When I wrote the original question I didn't know the regression
wouldn't work after the solution.) I have had to work on another
project here so haven't been able to keep up with the answers I get on
this list as fast as I would like to.

Is there any way to do a polynomial regression on real data after using
the method for getting around the extra zeros? That is the real
question. I will check out some of the recommendations posted so far
when I get this other project finished. Thank you all for the help. I
appreciate it.

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."
Andre Pavlov, Structural Engineer, Florida Department of Transportation
