lapy.io¶

Functions to read and write spectra and vertex functions.

lapy.io.read_ev(filename)¶

Load EV file.

Parameters:

filenamestr: Filename of input.

Returns:

d: dict: Dictionary of eigenvalues, eigenvectors (optional), and associated information.

lapy.io.read_vfunc(filename)¶

Import vertex functions from txt file.

Values can be separated by ; or , and surrounded by {} or () brackets. Also first line can have the keyword “Solution:”, i.e. the PSOL format from ShapeDNA.

Parameters:

filenamestr: Filename of input.

Returns:

valsarray: List of vfunc parameters.

lapy.io.write_ev(filename, d)¶

Save EV data structures as txt file (format from ShapeDNA).

Parameters:

filenamestr: Filename to save to.
ddict: Dictionary of eigenvalues, eigenvectors (optional), and associated information.

lapy.io.write_vfunc(filename, vfunc)¶

Save vertex in PSOL txt file.

First line “Solution:”, “,” separated values inside ()

Parameters:

filenamestr: Filename to save to.
vfuncarray_like: List of vfunc parameters.
