PlotSparse

plot the pattern of non nul elements of a sparse matrix

Calling Sequence

PlotSparse(A [,style])

Arguments

A

a sparse matrix

style

(optional) a string given the color and/or the marker type of the form "[color][mark]" where color may be a number referring the color you want to use (in the current colormap). If you use the std colormap then color may be one of the following letters :

k  for black       b  for blue
r  for red         g  for green
c  for cyan        m  for magenta
y  for yellow      t  for turquoise
G  a dark green

mark must be one of the following :

.  point           +  plus 
x  cross           *  circled plus 
D  filled diamond  d  diamond
^  upper triangle  v  down triangle
o  circle

by default you have "b." (in fact the 2d color) and this is also forced in case of error.

Description

plot the pattern of non nul elements of a sparse matrix : each non nul element is drawn with a marker. For "big" matrix use essentially the point . as marker

Examples

[A,description,ref,mtype] = ReadHBSparse(SCI+"/modules/umfpack/examples/arc130.rua");
PlotSparse(A,"y+")
xtitle(ref + "." + mtype + " : " + description)
