def read_funct_1d(file_name: str) -> Sequence[Union[float, int]]

def read_funct_1d_s(file_name: str) -> Union[float, int]

Description

The operator read_funct_1dread_funct_1dReadFunct1dReadFunct1dread_funct_1d reads the contents of FileNameFileNameFileNamefileNamefile_name and converts it into the function FunctionFunctionFunctionfunctionfunction. The file has be generated by write_funct_1dwrite_funct_1dWriteFunct1dWriteFunct1dwrite_funct_1d.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

FileNameFileNameFileNamefileNamefile_name (input_control)  filename.read → HTuplestrHTupleHtuple (string) (string) (HString) (char*)

Name of the file to be read.

FunctionFunctionFunctionfunctionfunction (output_control)  function_1d → HFunction1D, HTupleSequence[Union[float, int]]HTupleHtuple (real / integer) (double / int / long) (double / Hlong) (double / Hlong)

Function from the file.

Result

If the parameters are correct the operator read_funct_1dread_funct_1dReadFunct1dReadFunct1dread_funct_1d returns the value 2 ( H_MSG_TRUE) . Otherwise an exception is raised.
