Function Documentation

mhl()

double mhl	(	const gsl_vector *	beta,
		const gsl_matrix *	SigI
	)

Mahalanobis distance.

Calculates the Mahalanobis distance of a vector from zero.

Parameters

[in]	gsl_vector*	the vector
[in]	gsl_matrix*	the corresponding inverse-covariance matrix

Returns

a scalar value of type double.

printMat()

void printMat

(

const gsl_matrix *

m

)

Print matrix to screen.

Printing a GSL matrix to screen, with each row on a line, values seprated by spaces.

Parameters

[in]	gsl_matrix*	matrix to be displayed
[in]	double&	label for missing data

rdtsc()

unsigned long long rdtsc

(

)

Accessing the processor RTDSC instruction.

Returns

a value of type unsigned long long.

This function outputs the processor RTDSC instruction for use in seeding random number generators using assembly code.

Warning

this function is unlikely to work under Windows.
