fitbenchmarking.parsing.nist_data_functions module
Functions that prepare the function specified in NIST problem definition file into the right format for SciPy.
- fitbenchmarking.parsing.nist_data_functions.format_function_scipy(function)
Formats the function string such that it is scipy-ready.
- Parameters:
function (str) – The function to be formatted
- Returns:
The formatted function
- Return type:
str
- fitbenchmarking.parsing.nist_data_functions.is_int(value)
Checks to see if a value is an integer or not
- Parameters:
value (str) – String representation of an equation
- Returns:
Whether or not value is an int
- Return type:
bool
- fitbenchmarking.parsing.nist_data_functions.is_safe(func_str)
Verifies that a string is safe to be passed to exec in the context of an equation.
- Parameters:
func_str (string) – The function to be checked
- Returns:
Whether the string is of the expected format for an equation
- Return type:
bool
