Method Detail

instantiate

public static <U extends Unit<U>,S extends AbstractFloatMatrix<U,S>> S instantiate(float[][] value,
                                                                                   U unit,
                                                                                   StorageType storageType)
                                                                            throws ValueException

Instantiate the FloatMatrix based on its unit. Rigid check on types for the compiler.

Type Parameters:: U - the unit; S - the return type
Parameters:: value - the value; unit - the unit in which the value is expressed; storageType - whether the vector is SPARSE or DENSE
Returns:: an instantiated FloatMatrix with the value expressed in the unit
Throws:: ValueException - on vector init error

instantiateAnonymous

public static <S extends AbstractFloatMatrix<?,S>> S instantiateAnonymous(float[][] value,
                                                                          Unit<?> unit,
                                                                          StorageType storageType)
                                                                   throws ValueException

Instantiate the FloatMatrix based on its unit. Loose check for types on the compiler. This allows the unit to be specified as a Unit<?> type.
Note that it is possible to make mistakes with anonymous units. The following does compile:

 MoneyPerLengthUnit mlu = new MoneyPerLengthUnit(MoneyUnit.USD, LengthUnit.METER, "$/m", "$/m");
 
 MoneyPerArea mpa = FloatMatrixUtil.instantiateAnonymous(10.0, mlu);

Type Parameters:: S - the return type
Parameters:: value - the value; unit - the unit in which the value is expressed; storageType - whether the vector is SPARSE or DENSE
Returns:: an instantiated FloatMatrix with the value expressed in the unit
Throws:: ValueException - on vector init error

instantiateSI

public static <U extends Unit<U>,S extends AbstractFloatMatrix<U,S>> S instantiateSI(float[][] si,
                                                                                     U displayUnit,
                                                                                     StorageType storageType)
                                                                              throws ValueException

Instantiate the FloatMatrix based on its unit.

Type Parameters:: U - the unit; S - the return type
Parameters:: si - the value in SI units; displayUnit - the unit in which the value is expressed; storageType - whether the vector is SPARSE or DENSE
Returns:: an instantiated FloatMatrix with the value expressed in the unit
Throws:: ValueException - on vector init error

instantiateAnonymousSI

public static <S extends AbstractFloatMatrix<?,S>> S instantiateAnonymousSI(float[][] si,
                                                                            Unit<?> displayUnit,
                                                                            StorageType storageType)
                                                                     throws ValueException

 MoneyPerLengthUnit mlu = new MoneyPerLengthUnit(MoneyUnit.USD, LengthUnit.METER, "$/m", "$/m");
 
 MoneyPerArea mpa = FloatMatrixUtil.instantiateAnonymousSI(10.0, mlu);

Type Parameters:: S - the return type
Parameters:: si - the value in SI units; displayUnit - the unit in which the value is expressed; storageType - whether the vector is SPARSE or DENSE
Returns:: an instantiated FloatMatrix with the value expressed in the unit
Throws:: ValueException - on vector init error
