Description
As part of the alignment analysis, it would be useful to provide an interface to the legacy PolynomialMap class.
Would like to make an interface to the following functions:
- initialisation
Matrix<double> GetCoefficientsAsMatrix() const
: return a list of lists instead of matrix
- SetCoefficients(int point_dim): use a list of lists
void F(const double * point, double * value) const;
should take a list as argument (point) and return a list (value)
int PointDimension() const
int ValueDimension() const
std::ostream& operator<<(std::ostream&, const PolynomialMap&)
: should be used to make a str function
static PolynomialMap* PolynomialLeastSquaresFit(
const std::vector< std::vector<double> >& points,
const std::vector< std::vector<double> >& values,
unsigned int polynomialOrder,
const std::vector<double>& weights = std::vector<double>());
vectors should be lists or lists of lists
Nb the class is not in legacy, it is in src/common_cpp/Maths
So I have a pretty good first pass at bzr+ssh://bazaar.launchpad.net/~chris-rogers/maus/1731/
I have implemented and tested
- init
- get_coefficients_as_matrix
- evaluate (was F)
- least_squares_fit
I found that SetCoefficients throws an exception; I might have a look at that later on. But basically this is done and working.
- Status changed from Open to Closed
- % Done changed from 0 to 100
Closed at r914
I could at some stage add point_dimension, value_dimension str() interfaces; these can be got at by doing
len(p_map.get_coefficients_as_matrix()) # value_dimension
len(p_map.get_coefficients_as_matrix()[0]) # point_dimension
str(p_map.get_coefficients_as_matrix()) # string representation
so it would be more a convenience than anything else... and hence low priority
