DesignProxy

class DesignProxy(*args)

Design matrix cache.

Available constructors:

DesignProxy(x, basis)

DesignProxy(matrix)

Parameters
xSample

Input sample

psisequence of Function

Basis

matrix2-d sequence of float
The design matrix

Notes

Helps to cache evaluations of the design matrix. Can be useful for an iterative least squares problem resolution or in interaction with LeastSquaresMethod to select the algorithm used for the resolution of linear least-squares problems.

Methods

computeDesign(self, indices)

Build the design matrix.

getBasis(self)

Accessor to the basis.

getClassName(self)

Accessor to the object’s name.

getInputSample(self)

Input sample accessor.

getRowFilter(self)

Row filter accessor.

getSampleSize(self)

Sample size accessor.

getWeight(self)

Accessor to the weights.

hasRowFilter(self)

Row filter flag accessor.

hasWeight(self)

Weight flag accessor.

setRowFilter(self, rowFilter)

Row filter accessor.

setWeight(self, weight)

Accessor to the weights.

__init__(self, *args)

Initialize self. See help(type(self)) for accurate signature.
