Member Function Documentation

add()

template<typename Scalar >

void vcl::Distribution< Scalar >::add ( Scalar  v )

inline

Adds a value to the distribution.

Parameters

[in]

v

the value to add.

average()

template<typename Scalar >

Scalar vcl::Distribution< Scalar >::average ( ) const

inline

Returns the average of the values of the distribution.

Returns

The average of the distribution values.

max()

template<typename Scalar >

Scalar vcl::Distribution< Scalar >::max ( ) const

inline

template<typename Scalar >

uint vcl::Distribution< Scalar >::size ( ) const

inline

Returns the number of values of the distribution.

Returns

The size of the distribution.

standardDeviation()

template<typename Scalar >

Scalar vcl::Distribution< Scalar >::standardDeviation ( ) const

inline

Returns the standard deviation of the values of the distribution.

Returns

The standard deviation of the distribution values.

sum()

template<typename Scalar >
