Function Documentation

colCenter() [1/4]

void colCenter	(	const gsl_matrix *	source,
		gsl_matrix *	res
	)

Matrix centering with copy.

Parameters

[in]	gsl_matrix*	the matrix to be centered, left unmodified
[out]	gsl_matrix*	the modified matrix

colCenter() [2/4]

void colCenter	(	const gsl_matrix *	source,
		gsl_matrix *	res,
		const double &	absLab
	)

Matrix centering with copy and missing values.

In addition to centering does mean-imputation of missing values.

Parameters

[in]	gsl_matrix*	matrix to be centered, but not changed
[out]	gsl_matrix*	centered matrix
[in]	double&	label for missing values

colCenter() [3/4]

void colCenter

(

gsl_matrix *

inplace

)

Matrix centering in-place.

Parameters

[in,out]

gsl_matrix*

the matrix to be modified in-place

colCenter() [4/4]

void colCenter	(	gsl_matrix *	inplace,
		const double &	absLab
	)

Matrix centering in-place with missing values.

Parameters

[in,out]	gsl_matrix*	matrix to be modified in-place
[in]	double&	label for missing values

meanImpute()

void meanImpute	(	gsl_matrix *	inplace,
		const double &	absLab
	)

Mean imputation without centering.

Parameters

[in,out]	gsl_matrix*	matrix to be modified in-place
[in]	double&	label for missing values

vecCenter() [1/2]

void vecCenter	(	const gsl_vector *	source,
		gsl_vector *	res
	)

[out]	gsl_vector*	modified vector

vecCenter() [2/2]

void vecCenter

(

gsl_vector *

inplace

)

Vector centering in-place.

Parameters
