Chebyshev¶
Description¶
This function calculates a partial Chebyshev expansion
where
Coefficients
Chebyshev function has tree attributes (non-fitting parameters). First is ‘n’ which has integer type and sets the expansion order and creates n+1 expansion coefficients (fitting parameters). The parameter names have the form ‘Ai’ where ‘A’ is letter ‘A’ and ‘i’ is the parameter’s index starting from 0.
The other two attributes are doubles ‘StartX’ and ‘EndX’ which define the expansion (fitting) interval.
