`scipy.io._harwell_boeing.hb:hb_write`

source: /scipy/io/_harwell_boeing/hb.py :516

Signature

def hb_write ( path_or_open_file , m , hb_info = None )

Summary

Write HB-format file.

Parameters

path_or_open_file : path-like or file-like: If a file-like object, it is used as-is. Otherwise, it is opened before writing.
m : sparse array or matrix: the sparse array to write
hb_info : HBInfo: contains the meta-data for write

Returns

: None

Notes

At the moment not the full Harwell-Boeing format is supported. Supported features are:

assembled, non-symmetric, real matrices
integer for pointer/indices
exponential format for float values, and int format

Examples

We can read and write a harwell-boeing format file:

from scipy.io import hb_read, hb_write
from scipy.sparse import csr_array, eye
data = csr_array(eye(3))  # create a sparse array
hb_write("data.hb", data)  # write a hb file

✓

print(hb_read("data.hb", spmatrix=False))  # read a hb file

✗
