Abstract: In an example data processing method, a data processing task is received, which includes a to-be-processed non-polynomial function and to-be-processed data corresponding to an independent variable of the non-polynomial function. A first linear transformation is performed on the to-be-processed data, so that an independent variable value corresponding to data obtained after the first linear transformation falls within a fitting domain of definition.

The fitting polynomial is obtained by performing Chebyshev series fitting on the non-polynomial function in the fitting domain of definition.
