◆ evaluate()

ndarray::Array<double const,2,2> lsst::shapelet::GaussHermiteConvolution::evaluate ( afw::geom::ellipses::Ellipse ellipse) const

Evaluate a shapelet convolution matrix in the given array.

Parameters
[in,out]ellipseOn input, the ellipse core of the unconvolved shapelet expansion. On output, the ellipse core of the convolved shapelet expansion.

The returned array is owned by the GaussHermiteConvolution object and will be modified the next time evaluate() is called.

◆ getColOrder()

int lsst::shapelet::GaussHermiteConvolution::getColOrder ( ) const

Return the order of the to-be-convolved shapelet basis.

◆ getRowOrder()

int lsst::shapelet::GaussHermiteConvolution::getRowOrder ( ) const

Return the order of the post-convolution shapelet basis.
