For example, when a second order polynomial is selected and X and Y have 2 and 3 elements respectively and A is the matrix of model weights then:

 Y[0] = A[0][0] + A[0][1]X[0] + A[0][2]X[0]^2 + A[0][3]X[1] + A[0][4]X[1]^2
 Y[1] = A[1][0] + A[1][1]X[0] + A[1][2]X[0]^2 + A[1][3]X[1] + A[1][4]X[1]^2
 Y[2] = A[2][0] + A[2][1]X[0] + A[2][2]X[0]^2 + A[2][3]X[1] + A[2][4]X[1]^2
 

public FuncLinearCoeffC

FuncOrthPolynomialC()

Default constructor.
Creates an invalid handle.

FuncOrthPolynomialC(istream & strm)

Load from stream.

FuncOrthPolynomialC(BinIStreamC & strm)

Load from binary stream.

FuncOrthPolynomialC(int inSize,int outSize,UIntT order)

Construct an orthogonal polynomial of given 'order'.

bool SetTransform(const MatrixC & a)

Attempt to set transform matrix.

VectorC MakeInput(const VectorC & X) const

Expand vector to linear coefficients.

VectorC MakeJacobianInput(const VectorC & X,IntT i) const

Expand vector to linear coefficients.

UIntT NumberCoeffs(UIntT inputSize) const

Calculate the number of coefficents for a given input size.

VectorC Apply(const VectorC & data) const

Apply function to 'data'

SampleC<VectorC> Apply(const SampleC<VectorC> & data)

Apply transform to whole dataset.

VectorC operator ()(const VectorC & X) const

Evaluate Y=f(X)

MatrixC Jacobian(const VectorC & X) const

Calculate Jacobian matrix at X
Performs numerical estimation of the Jacobian using differences. This function has and should be overloaded for all cases where the Jacobian can be calculated analytically.

VectorMatrixC Evaluate(const VectorC & X)

Evalate the function and its jacobian at the same time.
This method defaults to calling 'Apply' and 'Jacobian' sperately.

UIntT InputSize() const

Size of input vector

UIntT OutputSize() const

Size of output vector

UIntT InputSize(UIntT inSize)

Set the input size.
This is for use of designer classes, changing the input size of an existing function has undefined effects.

UIntT OutputSize(UIntT outSize)

Set the output size.
This is for use of designer classes, changing the output size of an existing function has undefined effects.

bool Save(ostream & out) const

Save to stream 'out'.

bool Save(BinOStreamC & out) const

Save to binary stream 'out'.
