MatView: Scalable Sparse Matrix Viewer
MatView is a handy tool for viewing and exploring large sparse matrices.
Using MatView, a sparse matrix with millions of elements can be reduced
to a graphically viewable size
for overviews of the high-level structure,
or a detailed view can be obtained by zooming in and navigating
through small regions of the matrix.
- Scalability: Efficient Viewing of Very Large Matrices
(including new huge matrix file support!).
- Easy Thumbnail Navigation, and Zooming In & Out of Matrix Details.
- A Variety of Data Reduction Functions
(Avg, Min/Max, Sum, Std, Var).
- Custom Color Adjustments, or Greyscale Rendering.
- Viewing of Matrix Pattern Only, If Desired.
- Filtering of Matrix Values Outside the Color Map Range, if desired.
- Printing of Matrix Views, or Saving Views as PostScript / PPM.
- Compatibility with Matrix Market Format, Harwell-Boeing Format,
and Matlab MAT Files.
- Loading of Compressed or Gzipped Matrix Files.
The MatView 1.0 Beta 6 Software
(no longer Alpha, complete with new "configure" installation!)
is available for
FREE DOWNLOAD (gzipped tar format -
you can also download
Now Works with Tcl/Tk 8.4! :-D (12/3/2008)
(Now with smaller example matrices! :-)

Color Mapping Function Warping:
MatView is built using the Tcl/Tk
system, and so should theoretically run anywhere that Tcl/Tk runs...
(so far tested only on Unix platforms).
MatView is an ongoing project, with ever-continuing user
interface additions and improvements, and there are plans to add
pluggable modules for simple matrix transformations,
matrix graphing support, and support for more matrix file formats.
This work is preliminary and experimental,
and is intended only as an assistant to
more elaborate linear algebra solvers and systems.
Please feel free to download MatView, give it a try, and send me
back any feedback regarding its usefulness (or lack thereof :-).
