Show sparsity patterns of sparse matrices or write them to image files.
Example:
import betterspy
from scipy import sparse
A = sparse.rand(20, 20, density=0.1)
# betterspy.plot()
# set attributes on gca()
# plt.show()
# or directly
betterspy.show(A)
betterspy.write_png(
"out.png",
A,
# border_width=2,
# border_color="red",
# colormap="viridis"
) |
 |
|---|---|
| no colormap | viridis |
There is a command-line tool that can be used to show matrix-market or Harwell-Boeing files:
betterspy msc00726.mtx [out.png]
See betterspy -h for all options.
