                  double v)

Deprecated.

Set a value in this vector.

Parameters:

i - The index.

v - The value to set.

Returns:

The old value at i.

Throws:

IllegalArgumentException - if i is not a valid index in this vector.

add

public double add(int i,
                  double v)

Deprecated.

Add a value to an entry in this vector.

Parameters:

i - The index.

v - The value to set.

Returns:

The old value at i.

Throws:

IllegalArgumentException - if i is not a valid index in this vector.

fill

public void fill(double v)

Deprecated.

Fill the vector with a value.

Parameters:

v - The value with which to fill the vector.

set

public void set(Vec v)

Deprecated.

Parameters:

v - The array to copy in.

add

public void add(Vec v)

Deprecated.

Add another vector to this vector.

Parameters:

v - The other vector.

Throws:
