Method Detail

add

public void add(Measurement m)

Adds a measurement vector to this measurement. The measurements are assumed to have the same dimensions and units.

Parameters:

m - measurement to add

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object

integrate

public double integrate()

Returns the sum of the measurement vector elements. All dimensions are assumed to be of the same unit.

Returns:

sum of all vector elements

isEmpty

public boolean isEmpty()

Returns:

true if this measurement contains no data

mad

public void mad(Measurement m,
       double scale)

Scaled a measurement vector and adds it to this measurement. The measurements are assumed to have the same dimensions and units.

Parameters:

m - measurement to scall and add

scale - scale factor

mul

public void mul(double scale)

Scales a measurement vector by a single factor.

Parameters:

scale - the scaling factor

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
