Usually, you should call this method first with
" set to zero to determine the
number of coefficients used by the PolyMap. This allows you to allocate an array of the
correct size to hold all coefficient data. You should then call this method a second
time to get the coefficient data.

"ncoeff( nout 2 )
"is the number of coefficients to be returned. If a value of zero is supplied, no coefficient values are returned, but the number of coefficients used by the transformation is still returned in

If the supplied array is too short to hold all the coefficients, trailing coefficients are excluded. If the supplied array is longer than needed to hold all the coefficients, trailing elements are filled with zeros.
