Description Usage Arguments Value Examples

This script pre-processes a matrix by figuring out what the intervals of asymptotic stability are, as well as finding which perturbation values lead to a sign switch.

PreprocessMatrix(
  input_file,
  output_folder = NULL,
  prefix = NULL,
  max_bound = 10,
  zero_perturb = FALSE,
  threads = 1,
  verbose = FALSE
)

`input_file`	Input comma separated file for the jacobian matrix.
`output_folder`	Optional output folder to save python objects to disk. A number of files will be created in the form ‘output_folder/<prefix>_*.npy’. Default is NULL.
`prefix`	Prefix of output files, if you so choose.
`max_bound`	some of the matrices are unbounded stable towards one end, this is the limit the user imposes. Default: 10
`zero_perturb`	Flag to indicate you want to perturb the zero entries. Default: FALSE
`threads`	Number of threads to use. Default: 1
`verbose`	Default: FALSE

A list of with the following objects: matrix_size, column_names, row_names, non_zero, num_switch_functions, asymptotic_stability_start, asymptotic_stability_end, num_switch_funcs_r
