Show sparsity patterns of sparse matrices or write them to image files.

Example:

```python

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](https://math.nist.gov/MatrixMarket/) or

[Harwell-Boeing](https://en.wikipedia.org/wiki/Harwell-Boeing_file_format) files:

```

betterspy msc00726.mtx [out.png]

```

See `betterspy -h` for all options.
