	I've been using the DOS version since it came out and now use
Mathcad 3.1 for Windows/DOS and have recently purchased a Sun/SPARC
version (more on that later.)

	Although MathCad 3.1 has a subset of Maple (which I don't
use), I don't think of it as a computer algebra system.  I mostly use
it for simple data analysis (when verifying the performance of data
acq systems), for documentation, and for tedious calculations that
have to get revisited from time to time.

	I like the "report" output format, except that there is no
automatic method for generation of headers/footers or page numbers.
The tool boxes and online help are great. The GUI user interface is
fairly good (except I don't like the fact that when it generates an
error, it points to it, but the cursor is somewhere else....

> Wayne

	Now for my question: Anyone sucessfully using MathCad 3.1 on a
Sun/Sparc running 4.1..  with Openwindows 3.0?  I can't edit in the
file selection boxes (not really a big deal), and I can't use any of
the CONTROL keys (such as CTL-6 to get a superscript) which makes it
nearly useless. I'm still trying to sort this out with the support
folks, but (in part because I was away) its not done yet.

I haven't tried this, but doesn't Mathematica produce TeX output?  And
AmiPro accepts TeX input (for equation frames).

This is not possible in Maple V 1.1 for Windows, and we recognize
this as a shortcoming.  It will be fixed in Maple V Release 2 for
Windows.

Unfortunately, there is no way to speed up the plotting.  The redrawing
could be avoided by using bitmaps of each plot, but this rapidly
eats up memory, and overall efficiency is severly compromised.  We recognize
that this is not ideal, and this is an issue that is being worked on 
for Maple V Release 2 for Windows.

Hi Netters,

  I've stumbled on what appears to be a surprisingly intractable
problem.  Let us say that you are using a set of cubic spline
functions to define a path through a set of points.  Now you
want to know the total length of this path.  Simple, right?
For each spline function,

	 y = A + Bx + Cx^2 + Dx^3
so
	dy = [b + 2cx + + 3Dx^2]

so the path length is described by a differential equation of the form

	dl = SQRoot[ dx^2 + dy^2] = SQRoot[Q + Rx + Sx^2 + Tx^3 + Ux^4]dx

  I have come to despair of finding an indefinite or definite 
closed-form solution to the integral of dl.  Is there no 
alternative to integrating these spline functions numerically? (Ouch!)
I thought that cubic splines were pretty straightforward, but 
suddenly I'm in over my head.  If anyone has encountered this
problem before, or cares to make a suggestion, I would be grateful.

Hi!

I am using _Mathematica 2.1 for Windows_ and have a Hewlett Packard
Laserjet 4 (without the PostScript option) as my printer.

Since Mathematica produces all its graphics in the page description
language, PostScript, I haven't been able to print the graphics to
my printer from within Mathematica for Windows. So far, the only
way I have been able to print it is by "copying and pasting" the
graphics from Mathematica to a Windows based wordprocessor (I've
only tried it with Ami Pro 3.0 for Windows). However, the resolution
isn't too good when I print it thru the wordprocessor.

I was wondering whether anyone out there would be able to help in finding
out a way to print the graphics to my printer *DIRECTLY* from Mathematica
and thereby not losing any resolution.

Any help would be greatly appreciated.

Thanks!

- Sushim

I don't think you quite get the point. Yes, its symbolic capabilities
fall short of nearly anything else I have seen (incl Maple,
Mathematica, Derive etc). I have been using MathCAD as an
engineering tool since 88 - obviously for numerical applications. And
I always have been impressed about its abilities to solve and display
a solution. I have never liked the speed, though.

Symbolic algebra as such is a useful add-on to a program which is
really meant for something else. It saves me looking up all the
integration formulas and computing the determinant of a matrix.
And it still looks like I would write it on a scrap paper.

And thats where my maths capability stop anyhow. As you guessed, I am
an engineer rather that a mathematician. So I suggest you post above
letter in sci.engr. and you might find MathCAD users out there. You
might even find some in sci.maths.num-analysis.

Yours truly

We do not currently support Maple for DOS/Windows under OS/2, since
we have not been able to satisfactorily test it in that environment.
Users have reported that it will run, but we cannot verify this.

There is a package called JAKEF in the NETLIB collection which will
perform "automatic differentiation" on scalar- and vector-valued
functions of several variables, thereby yielding the gradient and
Jacobian, respectively.  The results are exact up to round-off error.
(I will post an "Introduction to NETLIB" document separately to this
news group.)

For symbolic differentiation in FORTRAN (often desirable for
optimization routines which need Jacobians and sometimes Hessians),
you might want to search the literature on the topic "automatic
differentiation", which refers to the process of taking a subroutine
that computes a given differentiable function and automatically
producing a second subroutine that computes the derivative of that
function by an exact rather than approximate method.  (There is a
description of this in the Spring '92 issue of the Maple Technical
Newsletter.)  You might also want to query sci.math.num-analysis on
the topic of "automatic differentiation".

Good luck,

REDUCE is widely used for Dirac Gamma matrix manipulations and runs 
on most commonly available machines from PC's to Supers like CRAY 
and Fujitsu (an information package can be obtained by sending the 
message 'send info-package' to reduce-netlib@rand.org). 
It currently has two packages (HEPHYS and CVIT) for high energy 
physics calculations. There is also a large bibliography of over 
700 papers referencing REDUCE, many in the high energy physics area.

Dear Hugh,

The routine "fit" in the Maple share library is hopefully what you need.
fit( X, Y, [1,t,t^2], t ); will return a quadratic polynomial in t which
fits the data X,Y in the least squares sense.
You can get the routine from the Maple share library using anonyous
ftp at daisy.uwaterloo.ca or ftp.inria.fr or neptune.inf.ethz.ch
It's the file maple/5.0/share/fit.  Alternatively, using e-mail, send an
message to maple-netlib@can.nl consisting of the text "send info".
