Method Detail

set

void set(int i,
       double v)

Set dimension i of the Vector to value v.

Parameters:

i - the index

v - value

add

void add(Vector that)

Adds the Vector that to this one in place: this += that.

Parameters:

that -

multAdd

void multAdd(double factor,
           ImmutableVector that)

this += factor * that.

Parameters:

factor -

that -

scale

void scale(double factor)

Scales this Vector: this *= factor.

Parameters:

factor - the scaling factor.

normalize

void normalize()

Normalizes the Vector according to the L2 norm.

newInstance

Vector newInstance()

Create a new instance of the current type. with elements being zero

Returns:

zero vector of current dimensionality
