Action: BF_COMBINED

Module	ves
Description	Usage
Combining other basis functions types

Details and examples

Combining other basis functions types

Examples

Here we define both Fourier cosine and sine expansions of order 10, each with 11 basis functions, which are combined. This results in a total number of 21 basis functions as only the constant from is bf_cos is used.

bf_cos: BF_COSINEFourier cosine basis functions. More details MINIMUMThe minimum of the interval on which the basis functions are defined=-pi MAXIMUMThe maximum of the interval on which the basis functions are defined=+pi ORDERThe order of the basis function expansion=10
The BF_COSINE action with label bf_cos calculates somethingbf_sin: BF_SINEFourier sine basis functions. More details   MINIMUMThe minimum of the interval on which the basis functions are defined=-pi MAXIMUMThe maximum of the interval on which the basis functions are defined=+pi ORDERThe order of the basis function expansion=10
The BF_SINE action with label bf_sin calculates somethingbf_comb: BF_COMBINEDCombining other basis functions types More details BASIS_FUNCTIONSLabels of the basis functions that should be combined=bf_cos,bf_sin
The BF_COMBINED action with label bf_comb calculates something

In principle this is the same as using BF_FOURIER with ORDER=10 but with different ordering of the basis functions. Note that the order used in BASIS_FUNCTIONS matters for the ordering of the basis functions, using BASIS_FUNCTIONS=bf_sin,bf_cos would results in a different order of the basis functions. This should be kept in mind when restarting from previous coefficients.
