Interfaces

public interface ply_legToPnt_2D

  • private subroutine ply_legToPnt_2D_singVar(fpt, legCoeffs, pntVal)

    Subroutine to transform Legendre expansion to point values at Chebyshev nodes.

    Arguments

    TypeIntentOptionalAttributesName
    type(ply_legFpt_type), intent(inout) :: fpt

    The FPT parameters.
    real(kind=rk), intent(inout) :: legCoeffs(:)

    The Legendre coefficients to convert to point values (Chebyshev nodes). \attention Although this array serves as input only, it is modified inside of this routine by the underlying FPT algorithm. So, when this routine returns from its call the original values of pntVal will be modified.
    real(kind=rk), intent(inout) :: pntVal(:)

    The resulting point values (Chebyshev nodes).

  • private subroutine ply_legToPnt_2D_multVar(fpt, legCoeffs, pntVal, nVars)

    Subroutine to transform Legendre expansion to point values at Chebyshev nodes.

    Arguments

    TypeIntentOptionalAttributesName
    type(ply_legFpt_type), intent(inout) :: fpt

    The FPT parameters.
    real(kind=rk), intent(inout) :: legCoeffs(:,:)

    The Legendre coefficients to convert to point values (Chebyshev nodes). \attention Although this array serves as input only, it is modified inside of this routine by the underlying FPT algorithm. So, when this routine returns from its call the original values of pntVal will be modified.
    real(kind=rk), intent(inout) :: pntVal(:,:)

    The resulting point values (Chebyshev nodes).
    integer, intent(in) :: nVars

    The number of scalar variables to transform.
