Description

transform_funct_1dtransform_funct_1dTransformFunct1dTransformFunct1dtransform_funct_1d transforms the input function FunctionFunctionFunctionfunctionfunction using the transformation parameters given in ParamsParamsParamsparamsValparams. The function FunctionFunctionFunctionfunctionfunction is passed as a tuple (see create_funct_1d_arraycreate_funct_1d_arrayCreateFunct1dArrayCreateFunct1dArraycreate_funct_1d_array and create_funct_1d_pairscreate_funct_1d_pairsCreateFunct1dPairsCreateFunct1dPairscreate_funct_1d_pairs). The following model is used for the transformation between the two functions (see match_funct_1d_transmatch_funct_1d_transMatchFunct1dTransMatchFunct1dTransmatch_funct_1d_trans): The output function TransformedFunctionTransformedFunctionTransformedFunctiontransformedFunctiontransformed_function is obtained by transforming the x and y values of the input function separately with the above formula, i.e., the output function is not sampled again. Therefore, the parameter is restricted to . To resample a function, the operator sample_funct_1dsample_funct_1dSampleFunct1dSampleFunct1dsample_funct_1d can be used.

Execution Information

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