We have made some significant improvements to the performance of the
FFT functions in O-Matrix for the next release but we have been
profiling "real world" applications to see what other areas in
relation to the use of FFTs may be enhanced.

If you have a "FFT-centric" application it would be greatly
appreciated if you forward me a stand-alone sample of your application
which we may use for profiling purposes.

Thanks,
Beau

Greetings O-Matrix users,

Early this week version 2.1 of the Statistical Time Series Analysis
toolbox was released for O-Matrix. This release offers a couple of
major modeling enhancements and several other minor updates.
Specifically, the new version of STSA contains two new directories,
NONPAR and POD that extend modeling with STSA for nonlinear and
nonparametric time series (NONPAR) and for series that are
decomposable into trends and cyclical components (POD).

The NONPAR directory contains functions that are adapted from the
book of Fan and Yao "Nonlinear TIme Series: Parametric and
Nonparametric Models", Springer-Verlag, 2003, and are suitable for a
wide variety of problems were a parametric form for modeling is
either not appropriate or not desirable. Many of the functions in
NONPAR are not directly available in other software programs - in
addition, they offer automated bandwindth selection and forecasting
with ease. Most functions also offer automatic plotting options.

The POD directory contains functions for analyzing time series using
the method of Singular Spectrum Analysis (SSA) which is mainly
suitable for series that exhibit trends and cyclical components which
we wish to extract and possibly to forecast separately. SSA has been
proven successful in many modeling situations, especially in the
natural sciences.

If you have any comments or recommendations about this new release of
STSA, including bugs, or about potential future enhancements that you
may find useful in your line of work I would be happy to know about
them.

Happy computing!

Dimitrios D. Thomakos
STSA developer

I went into mlmode and try to "load myfile" where myfile is a .mat
file, but Omatrix doesn't understand load. I could have switched to
Omatrix mode and use mfread instead, but is there a simpler way?

We have been adding some user stories to the site and those will be
updated soon.  Also, if you have O-Matrix results and/or code on your
website, please post those links here.

Harmonic Software has announced the release of version 2 of
STSA, The Statistical Time Series Analysis Toolbox for O-Matrix.
This release includes a significant number of additions and
enhancements. STSA v2 includes new functions for filtering,
optimization, random number generation, and specialized statistics.
For more details on what's new see the O-Matrix home page at:
http://www.omatrix.com/stsaV2.html

The STSA toolbox is a collection of O-Matrix functions for
analyzing time-dependent observations (time series).
The functions can be used to perform a large variety of different types of
analysis, including descriptive and graphical analysis, model
identification,
fitting and forecasting, residual diagnostic checking, spectral analysis,
filtering and smoothing, optimization etc. The functions of the
toolbox combine breadth of applications, ease of use and the speed
and computing power of O-Matrix to provide you with an integrated working
environment for analyzing your time series data. The functions can be easily

incorporated into other functions by the user thus limiting the time needed
for writing programs or prototyping new routines. The STSA toolbox has
functions that cover most of standard time series analysis plus a number of
related functions not directly found in the main O-Matrix distribution or
related products. The distribution includes numerous examples using
real-world
and simulated data that is provided and can be used as a starting point for
immediately using the power of STSA.

Pricing and detailed product information for STSA is available on the
O-Matrix home page, http://www.omatrix.com/stsa.html

I have attached a function for writing XLS files.  Save the file to your
omwin\function directory and it will automatically available as xlwrite().
We have received a significant number of requests for this and it will be in
the next O-Matrix release.

The lp_solve Linear Programming solver is now bundled
with the O-Matrix Light download.  Installing O-Matrix
Light installs and configures everything necessary
to be up and running using the lp_solver from the
high-performance O-Matrix environment.

The download includes extensive documentation and examples
of lp_solve, and implementing Linear Programming problems
with O-Matrix and the solver.  The lp_solve
package solves pure linear, mixed integer/binary, semi-continuous
and ordered sets models. lp_solve has no limit on model size
and has solved models with more than 100000 constraints.

The O-Matrix platform provides an ideal framework both for
creating turnkey, re-distributable applications, and for
performing exploratory analysis and problem solving.

The key is

window_coord = gcoord(x, y),

which will return the relative coordinates for input to

gaddtext(text, window_coord, text_coord, direction)
.
Online references:
http://www.omatrix.com/manual/gaddtext.htm
http://www.omatrix.com/manual/gcoord2.htm
.

Consider the function
gaddtext(text, window_coord, text_coord)

window_coord refers to the plotted area in relative coordinates [x, y]
where x and y vary from zero to one.

Is there any way to query O-matrix as to the min and max coordinate
values in x and y, so that plotted values can be converted to the
needed relative coordinates?

There could be alternate answers, really, such as a way to query the
axis limits, or a function to do the whole conversion.

Obviously in many cases it is possible to know what the axis limits
will be, or to set them, but it is more general if I can query to find
out.

Thank you.

	 if tp == 0.0 then gbar(y,m)
	 else gbar(ry,m)
end

Hi
Has anyone developed some code to plot up a histogram?
The "ghist" function is a little too sophisticated in that the width
or size of the bins is adjusted to have equi-sized samples in each bin.

I want the bins to simply have a constant width.

Dear O-Matrix User:

We are in the process of updating the current version of STSA, The
Statistical Time Series Toolbox for O-Matrix. User comments and feedback
about the advantages, problems and potential of STSA are a crucial and
integral part in our development process.

Have you purchased a license for STSA?  If not, is it because you do not
need these types of functions for your analysis, or did you find the toolbox
incomplete for your desires?

Much appreciated,
Beau Paisley
