Problem scaling routines¶

Problem.set_rii(row, double sf)¶

Set (change) row scale factor

Parameters:	row (`int` or `str`) – the index or name of the row sf (`Real`) – the scale factor

Problem.set_sjj(col, double sf)¶

Set (change) column scale factor

Parameters:	col (`int` or `str`) – the index or name of the column sf (`Real`) – the scale factor

Problem.get_rii(row)¶

Retrieve row scale factor

Parameters:	row (`int` or `str`) – the index or name of the row
Returns:	the scale factor
Return type:	`float`

Problem.get_sjj(col)¶

Retrieve column scale factor

Parameters:	col (`int` or `str`) – the index or name of the column
Returns:	the scale factor
Return type:	`float`

Problem.scale_prob(*algorithms)¶

Scale problem data

Parameters:	algorithms – the algorithms to apply, one or more from `'auto'`, `'skip'`, `'geometric'`, `'equilibration'`, `'round'`
