Description

transform_funct_1dtransform_funct_1dtransform_funct_1dTransformFunct1dTransformFunct1d transforms the input function FunctionFunctionFunctionFunctionfunction using the transformation parameters given in ParamsParamsParamsParamsparamsVal. The function FunctionFunctionFunctionFunctionfunction is passed as a tuple (see create_funct_1d_arraycreate_funct_1d_arraycreate_funct_1d_arrayCreateFunct1dArrayCreateFunct1dArray and create_funct_1d_pairscreate_funct_1d_pairscreate_funct_1d_pairsCreateFunct1dPairsCreateFunct1dPairs). The following model is used for the transformation between the two functions (see match_funct_1d_transmatch_funct_1d_transmatch_funct_1d_transMatchFunct1dTransMatchFunct1dTrans): 

    yt(x) = a1*y(a3*x+a4)+a2 .

The output function TransformedFunctionTransformedFunctionTransformedFunctionTransformedFunctiontransformedFunction 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 3 is restricted to a3!=0.0. To resample a function, the operator sample_funct_1dsample_funct_1dsample_funct_1dSampleFunct1dSampleFunct1d can be used.
