[mathcad] Re: Range Variable Problem

After correcting the Vx, you then have the Mathematical problem that there are NO polynomial solutions (integer positive powers) where real values of 'x' produce complex results, so the regress fails!

In your example you have made vx a range variable, not a vector [your sheet says vx:=k], so use vx[k:k
i.e. vx vector-subscript k := k
the value of the vector vx at location k is made equal to k, and as k runs through its whole range.

Thanks, Colin for the reply.

Now how do I get a polynomial regression to work with the new restricted
range vectors?

See attached.

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
