Description

The Cheby function evaluates a Chebyshev polynomial at a specific value .

Example

<Force_Vector_TwoBody

    id                    = "30101"

    type                  = "ForceOnly"

    i_marker_id           = "30102031"

    j_floating_marker_id  = "30101031"

    ref_marker_id         = "30101010"

    fx_expression         = BISTOP(DX(30102030,30101010,30101010),
                            VX(30102030,30101010,30101010),0.5,9.5,10000000,2.1,1,0.001)"

    fy_expression         = "0"

    fz_expression         = "0"

Arguments

The independent variable.  For example, to specify time as the independent variable, specify as TIME.

The phase shift in the Chebychev polynomial.

The coefficients in the Chebychev polynomial.  Specify only as many coefficients as needed with a maximum of 31 coefficients.
