Method Summary

double[]	asArray() get the data
Vec	copy() return a copy of this, or some version that the user can manipulate at will.
double	get(int i) the i-th element
void	set(double[] d) Copy the vector from an array
void	set(int i, double d) set the i-th element
void	set(Vec v) Copy the vector from an array
int	size() the size of the vector

Method Detail

size

int size()

the size of the vector

get

double get(int i)

the i-th element

set

void set(int i,
         double d)

set the i-th element

Parameters:

i - the element to set

d - the value to set it to

Throws:

java.lang.UnsupportedOperationException - if the vector is immutable

set

void set(double[] d)

Copy the vector from an array

Parameters:

d - the array to copy from

Throws:

java.lang.UnsupportedOperationException - if the vector is immutable

set

void set(Vec v)

Copy the vector from an array

Parameters:

v - the vector to copy from

Throws:

java.lang.UnsupportedOperationException - if the vector is immutable

copy

Vec copy()

return a copy of this, or some version that the user can manipulate at will. If the implementation of this is immutable, can return the original, or the implementation can do some kind of copy-on-write.

Returns:

a copy of the data

asArray

double[] asArray()

get the data

Returns:

the data as a double[]
